Foreign government workers working in the US under A, G or E visas may enjoy diplomatic rights and immunities, such as an exemption from US income taxes. If foreign workers want to become permanent residents of the US, they need to adjust their status and they must waive their special rights. Since France and the US have a special agreement, French Nationals who get a salary from the Republic of France must file I-508F (Waiver of Rights, Privileges, Exemptions, and Immunities) when filing Form I-485 or Form I-131. This form is needed for compliance with Section 247(b) of the Immigration and Nationality Act (INA) as well as relevant conventions between France and the US regarding property and taxes.
