Gather Vital Documents
In order to expedite your loved one's potential release from custody, the most important first step is to gather any and all documentation or evidence you have which indicates your loved one's immigration status, their immigration history, criminal history, travel history and ties to the community including family, friends, employment and other similar information. Additionally, basic identification documents including green cards, passports, visas, and birth certificates may prove quite helpful to the immigration lawyer you may ultimately hire to untangle your loved one from this mess.
Get the A Number
The A number - also known as the Alien Registration Number, is an 8 or 9 digit number which is found on nearly every document issued by USCIS. If your loved one has at any time been granted a legal immigrant or non-immigrant status you may be able to locate this number to provide to the lawyer. Alternatively, if your loved one has not previously had any type of status,or you simply cannot locate the relevant documents, your loved one may know his/her A number. Therefore, this should be one of the first questions to ask them if they contact you while detained.
Consult with a Qualified Immigration Attorney
The law and policies surrounding ICE detainers is particularly specialized, involving a unique balancing of federal regulations and local practice and procedure. An immigration attorney with substantial experience in the specific areas of detention and removal will be able to leverage the resources and information you provide to maximize your loved ones opportunities to obtain release from custody.
