Form I-508F is used by French nationals who receive a salary from the Republic of France while living in the United Sates and working at a French mission. Form I-508F is used to comply with Section 247(b) of the Immigration and Nationality Act and the Convention between France and the United States. Form I-508F deals specifically with income taxes and taxes on property. French nationals who complete Form I-508F must also complete Form I-508 and file both forms simultaneously.

The French national completing Form I-508F must indicate that he or she is a French national, has an occupational status that entitles the applicant to non-immigrant classification as a Government Official or International Organization Representative under Section 101(a), paragraphs 15(a) and 15 (g) of the Immigration and Nationality Act.

In order to gain admission or retain the status as a lawful permanent resident, the French national must indicate on Form 1-508F that he or she is waiving all rights, privileges, exemptions and immunities that he or she would be entitled to under United States laws or executive orders.

Form I-508F requires the applicant to chose whether he or she waives or does not waive the benefits conferred by Articles 16 and 21 of the Convention between the United States and France.
