Yes, in most cases you can send a letter or message written in Arabic to an inmate housed at a United States Penitentiary (USP), including federal prisons operated by the Bureau of Prisons (BOP). However, there are a few important things to understand before sending foreign-language correspondence.
All inmate mail entering a USP facility is screened and monitored by prison staff for safety and security reasons. When a letter is written in a language other than English, including Arabic, the mailroom may hold the correspondence longer so it can be reviewed or translated if necessary. This does not automatically mean the mail will be rejected. It simply means the facility may need additional time to inspect the content.
In most federal prisons, inmates are allowed to receive personal correspondence in foreign languages as long as the content does not violate institutional rules. Problems typically only arise if the message contains threats, coded language, gang references, escape plans, prohibited business activity, or anything that could present a security concern. Religious greetings, family communication, encouragement, and normal conversation are generally permitted.
If you are using a service like InmateAid to send the letter, the message will still be printed and mailed through USPS like regular inmate mail. The prison’s mailroom staff then reviews and distributes it according to BOP procedures. Because Arabic mail may require additional review, delivery can sometimes take longer than standard English-language correspondence.
