How to locate or contact a detainee
To locate someone in ICE custody, use the ICE Online Detainee Locator System at locator.ice.gov. You will need the person’s A-number (Alien Registration Number) and country of birth, or their full name, country of birth, and date of birth.
To ask whether someone is held here, and to leave an urgent message for a detainee, ICE publishes one number: (936) 521-4900. Give the detainee’s full name, alien registration number (A-number), your own name, and a phone number where you can be reached; the facility passes the message on. Detainees cannot receive incoming calls — they place outgoing calls themselves. Have the person’s biographical information ready when you call (full legal name and any aliases, date of birth, and country of birth). ICE says to call that line between 8 a.m. and 5 p.m. ICE says the facility has ICE tablets, and that information on sending a detainee a non-confidential message is in the GettingOut help center (gettingout.com).
Visiting in person
ICE’s page for this facility (last updated 08/18/2026, checked October 7, 2026) publishes a friends-and-family schedule “Effective August 31, 2026.” All family and other social visits are non-contact and first come, first served. Each detainee is allowed one social visit a week, and visitors must arrive 30 minutes before the visiting time to sign in and clear security. On request, the facility may let two adults into the visiting booth at a time, sharing the phone; parents must supervise children at all times.

ICE prints the numbers in parentheses without explaining them. ICE’s page also says the current low-level housing units are H-6, H-7 and H-8 only, that the facility administrator may alter, cancel or suspend visits in extreme circumstances (such as extreme weather, a security threat or a health crisis), and that housing schedules are subject to change without notice, so contact the facility at (936) 521-4900 to confirm before you travel.
Rules for visitors (as ICE lists them): no firearms or weapons of any kind anywhere in the facility; no electronic devices (cell phones, pagers, radios) in the secure areas; everyone entering is subject to a pat-down, a search of belongings and a metal scan, and anyone who refuses a reasonable search is not admitted. Visitors who are or appear intoxicated are turned away, and nothing may be passed to a detainee. A small wallet or change holder is allowed, and visitors with infants may bring no more than three diapers and two baby bottles. ICE lists as not allowed inside: packages, cell phones, smart watches, mail or magazines, purses or briefcases, diaper bags, strollers, cameras, toys or dolls, photographs or photo albums, and tobacco products. The dress code bars shorts and swimwear for visitors 12 and older, requires shoes at all times, and bars open-toe or open-heel shoes and Crocs; ICE’s page has the full code by age and sex. ICE lists free public parking on the premises.
| Visit type | What ICE publishes for this facility |
|---|---|
| Attorney or legal representative | In person 7 a.m. to 7 p.m., 7 days a week, including holidays |
| Consular officials | Any time. ICE asks that arrangements be made in advance, to the extent possible, with the ICE Supervisory Deportation Officer in charge of the facility, at (936) 520-5816, and that officials bring appropriate credentials |
| Clergy | Any time, by prior arrangement with the Chaplain’s Office at (936) 521-4900 ext. 4971 |
Sending mail, commissary funds, and personal items
Letters and packages sent to a detainee must identify the detainee and show the sender’s name and return address (this facility’s own format is below) — and each facility publishes its own exact format: some also require a housing-unit number, and facilities run by the federal Bureau of Prisons use the BOP register number instead. ICE lists each facility’s format on that facility’s page at ice.gov. This facility’s own ICE page says incoming mail “is not read upon opening, only inspected by the delivering officer” and that detainees may seal their own outgoing letters. ICE’s detention standards allow more than that. ICE’s inspectors say this facility operates under the Performance-Based National Detention Standards (PBNDS) 2011 (Revised 2016) (see the inspection record below). Under that standard’s mail section, 5.1, staff open and inspect incoming general correspondence for contraband in the detainee’s presence unless the facility administrator authorizes otherwise, and it “may be read to the extent necessary to maintain security, as authorized by the facility administrator” — reading, with the administrator’s approval, may be done at random. Outgoing general mail may be inspected or read if it is addressed to another detainee or there is evidence it might threaten the facility’s secure or orderly operation, endanger the recipient or the public, or facilitate criminal activity. Only special correspondence or legal mail — mail to or from attorneys and other legal representatives, government attorneys, judges and courts, embassies and consulates, the President and Vice President, members of Congress, the Justice Department and DHS (including ICE, ERO, ICE Health Services Corps, CRCL and the DHS Inspector General), outside health care professionals, grievance administrators and the news media — may not be read: the envelope must be labeled “special correspondence” or “legal mail” and identify the sender’s or addressee’s title and office. Staff may neither read nor copy it; any inspection takes place in the detainee’s presence and is limited to detecting physical contraband and confirming that enclosures qualify as special correspondence or legal mail. Rules for commissary (account) deposits and permitted personal items vary by facility, and so does the number that handles them — ICE names a separate facility mail clerk on some facility pages. This facility’s deposit route, accepted form of payment and contacts are in the Sending Items to Detainees section of its own ICE page (linked above).
What ICE publishes for this facility’s mail, money, and packages
- Letters must include the last four digits of the detainee’s A-number, plus the sender’s name and address. ICE gives this format: Montgomery Processing Center, [detainee’s full name and last four digits of the A-number], 806 Hilbig Road, Conroe, TX 77301. Outgoing mail is routed to the post office within 24 hours of receipt by facility staff, and a mail pick-up and delivery schedule is posted in the housing units.
- Money: ICE lists Access Corrections by phone at 1-866-345-1884 or online, or a money order by U.S. Postal Service to Montgomery Processing Center, 806 Hilbig Road, Conroe, TX 77301, referencing the detainee’s name. ICE’s note: a cashier’s check or money order must include the detainee’s full name and A-number. Funds received in the mail are taken to the processing area to be placed on the account, with a receipt from the processing officer; detainees are cautioned not to have cash sent to them in the mail.
- Packages: limited to items needed solely for travel or release from custody, with the ICE Deportation Officer’s approval. Before sending one, ICE says to contact the facility’s mail room supervisor at (936) 521-4900 ext. 4011.
- Stamps: detainees may buy them; indigent detainees (no means of support and no funds in their facility account) get a postage allowance at government expense.
- Transfers and departures: only legal mail is forwarded; general correspondence is returned to sender.
- Luggage for removal: one small piece is allowed; if the person has none, luggage can be sent or delivered after approval from the Supervisory Deportation Officer. No electronic devices (cell phones, electric razors, laptops, radios) are accepted.

Legal access, attorneys, and immigration court information
Detainees have the right to speak with an attorney, and attorney–client visits and calls are confidential. For information about a case before the immigration court (EOIR), EOIR’s automated line 1-800-898-7180 (toll-free, 24 hours a day, English and Spanish) gives the next hearing date and case status; callers enter the 9 digits of the A-number, without the letter A (EOIR, checked October 24, 2026). For a matter before the Board of Immigration Appeals (BIA), the main line of EOIR (the Justice Department agency the BIA belongs to) is (703) 305-0289. Applications for relief from removal must be filed directly with the immigration court handling the case. If you cannot afford an attorney, the immigration court can provide a list of pro bono legal service providers — see the related resources below.
Legal visits, video calls and legal documents
ICE’s page for this facility publishes these channels for legal representatives (checked October 7, 2026):
- Case information: requests about people detained here go to Houston.Outreach@ice.dhs.gov. ICE notes that this mailbox does not accept applications for a stay of removal or case appeals.
- Deportation Officer: to learn who a client’s Deportation Officer is, ICE says to contact ERO Houston, Montgomery Processing Center, at (936) 520-5700; a G-28 must be on file before any information is disclosed.
- G-28s can be submitted through ICE’s online platform ERO eFile. Facility staff do not have access to ERO eFile, so representatives should bring a downloaded copy of the submitted G-28 to any in-person or remote legal visit.
- Video visits, legal calls and confidential documents: all requests for legal visits, legal calls, and the exchange of confidential documents (for example, to obtain signatures) go by email to MPC-Legal@geogroup.com. Requests for legal video visits/calls must be made at least 24 hours in advance and no more than two weeks ahead, during business hours (Monday to Friday, 8 a.m. to 5 p.m., excluding holidays); video visits are scheduled in 30- to 60-minute increments, no representative may have more than one 60-minute appointment with a detainee in a single day, and a visit that has not begun within 15 minutes of its start time is canceled. The request must include a copy of the attorney’s driver’s license, bar card and a G-28/E-28. Only attorneys, law-firm staff assisting on the case, interpreters, mental health evaluators and the detainee may take part; no family members, and no video or audio recording.
- How documents are handled: ICE says a reasonable amount and size of documents will be accommodated. ICE says staff may open incoming legal mail in the detainee’s presence and inspect it for contraband, but will not store, read, translate or explain the documents. Representatives should say in the request how electronic documents are to be handled (for example, whether the original goes to the detainee, is scanned and emailed back, and whether it is shredded or returned to the detainee after scanning). ICE says the email address is not for communication with the immigration court or ICE officers.
Immigration court and free legal providers (Conroe Immigration Court)
ICE says a list of pro bono (free) legal organizations, updated quarterly, is posted in the housing units, and that it is the detainee’s own responsibility to contact a provider for an appointment. ICE’s facility page does not name the immigration court that hears the cases of people held here, but EOIR’s Conroe Immigration Court is at 806 Hilbig Road, Suite 2-300, 2nd Floor, Conroe, TX 77301 — the facility’s own street address — and EOIR says it is located in a DHS-controlled detention facility (as of October 7, 2026, the court’s page links to ICE’s Houston Contract Detention Facility page for entry information). EOIR lists public and window-filing hours of 8 a.m. to 4 p.m., Monday to Friday except federal holidays, and the general-inquiry email Conroe.Immigration.Court@usdoj.gov. The court that actually hears a given case may still be a different one; confirm it from the A-number through EOIR’s hotline at 1-800-898-7180. On the October 2026 edition of EOIR’s List of Pro Bono Legal Service Providers, the entries under Conroe Immigration Court are:
| Provider | Contact EOIR lists | Notes EOIR records |
|---|---|---|
| ABA Commission on Immigration Detention Information Hotline (referral service) | From inside an ICE facility, speed dial 2150#; on someone else’s behalf, email immcenter@americanbar.org | Pro se case assistance for detained respondents only |

ICE inspection record
ICE’s Office of Detention Oversight (ODO), part of ICE’s Office of Professional Responsibility, inspected this facility on April 28–30, 2026 (ODO report, Inspection 2026-002-131). What the report says:
- Who runs it: the facility opened in 2018 and is owned and operated by The GEO Group, Inc., under ERO Houston, which began housing detainees there in 2018. It is a dedicated ICE detention facility operating under the Performance-Based National Detention Standards (PBNDS) 2011 (Revised 2016), and it holds male and female detainees of low, medium-low, medium-high and high security classification for periods longer than 72 hours.
- Staffing and services: an ERO assistant field office director, supervisory detention and deportation officers, and deportation officers are assigned full time, on site Monday through Friday, 8 a.m. to 5 p.m. GEO provides food service, ICE Health Service Corps provides medical care, and Keefe Commissary Network provides commissary. The facility was accredited by the American Correctional Association in November 2020 and the National Commission on Correctional Health Care in June 2024, and was DHS PREA certified after an August 2023 audit.
- Findings: compliant with 28 of 29 standards reviewed; 1 deficiency, not a priority component and not a repeat: Food Service — turkey bologna stored in 6-inch pans in the refrigerated storage cooler at 44.5°F, when the standard requires perishables to be stored at 35–40°F.
- Detainee interviews: ODO interviewed 35 detainees; none alleged discrimination, mistreatment or abuse, and all 35 reported satisfaction with facility services.
- Rating: Superior. At the previous inspection (fiscal year 2025), ODO reviewed 28 standards, found no deficiencies and also rated the facility Superior. ICE’s inspection index lists that earlier inspection as December 3–5, 2024 (report); the April 2026 report’s text calls it “December 2025”.
ODO redacts bed-capacity and population counts in the published report; for population, see the ICE statistics box above. ICE lists every posted report on its ODO facility inspections page.
Earlier inspection — May 14-16, 2024. The ODO follow-up compliance report records:
- Scope and findings: 18 standards reviewed, compliance with 16, and three deficiencies in the remaining two standards.
- Visitor records: in 13 out of 32 visitor-log entries, staff did not record the required vehicle information in the appropriate columns.
These are historical findings from the May 2024 inspection.
