Immigration specialists are typically lawyers or paralegals at law firms who assist foreign nationals with immigration procedures. They help applicants apply for work permits, citizenship, adoptions, or deal with homeland security issues. Specialists are different than immigration officers, who complete BASIC immigration officers’ training through USCIS and are often stationed at border entry, or in immigration offices. Job responsibilities of specialists can include submitting or appealing petitions, defending immigrants against fraud claims, or providing guidance about current policies to clients or their legal teams.
