Foreign government workers who work in the US often do so under A, G or E nonimmigrant visa status. These workers enjoy certain privileges and rights, which may include diplomatic rights and immunities and an exemption from US income taxes. In cases where such workers wish to adjust their status and become permanent residents of the US, they must waive these rights. To do this, they must file I-508 (Waiver of Rights, Privileges, Exemptions and Immunities (Under Section 247(b) of the INA)) in order to do so. The filing of this form attests that the applicant gives up all diplomatic rights and agrees to pay US income taxes in order to apply for permanent residency.
