A biometric appointment is required when using Form I-131 to apply for a reentry permit or a refugee travel document, reports U.S. Citizenship and Immigration Services. Applicants requesting reentry permits must keep their biometric appointments before leaving the United States, according to Immigration Direct.
Form I-131 is used for immigrant and non-immigrant travel documents for activities such as allowing permanent or conditional residents to leave the United States and return without the need to acquire a returning resident visa, explains USimmigration.com. This gives refugees or asylum seekers the ability to temporarily leave and return to the United States, and it permits an inadmissible alien to temporarily enter the United States.
Although applicants can initially file Form I-131 and pay the required fees online, they must afterward mail supporting documents to an address provided on the application confirmation receipt, as reported by U.S. Citizenship and Immigration Services. Additionally, they are sent a notice of appointment to appear at an application support center for biometric services. The filing fee paid online includes a fee for submission of the form and an additional fee for the biometric appointment. Biometric services are required for those between the ages of 14 and 79, but are not required for children or those over 80 years old.
