You have to file Form I-131 to apply for a re-entry permit, refugee travel document or advance parole travel document, to include parole into the US for humanitarian reasons.
Advance Parole is for applicants who have a pending Form I-485, Application to Adjust Status to Permanent Resident, and who want to travel before the Application is approved. A Refugee Travel Document is for applicants who hold Refugee or Asylee status and who want to travel outside the US. Re-entry Permit is for Lawful Permanent Residents who will be abroad for an extended period of time, generally one year or more.
If you are filing Form I-131 based on your pending or approved Form I-821, you are required to file form I-131 with the USCIS Dallas Lockbox facility. Make sure you include a copy of the I-797 C Notice of Action that shows that your application was accepted or approved. If you are applying for renewal of your advance parole document , the USCIS will accept and adjudicate Form I-131 filed up to 120 days before the date your current Advance Parole document expires.
All Refugee Travel Document applicants or one for a Reentry Permit must complete biometrics at an Application Support Center (ASC) or if applying for a Refugee Travel Document while outside of the U.S. at an overseas USCIS facility. If you are between 14 and 79 years of age and you are applying for a Refugee Travel Document or Re-entry Permit, you must also be fingerprinted as part of USCIS biometric services requirements. After you have filed this application, USCIS will inform you in writing of the time/location of your biometrics appointment. It is important to remember that if you do not appear to be fingerprinted or for other biometric services, it might lead to denial of your application.
Applicants for Re-entry Permit and/or Refugee Travel Documents between 14 and 79 years of age have to pay the additional $85 biometric fee. The submission fee while filing for advance parole or re-entry permit is $360 and for a Refugee Travel Document for an individual aged 16 or older is $135. For a child under the age of 16 years, it is $105. For individuals aged between 14 and 79, a biometric fee of $85 is necessary for a Reentry Permit and a Refugee Travel Document , unless the applicant resides outside of the US at the time of filing their form. Note that there is no biometric fee required for advance parole applicants. The submission fee and biometrics services fee may be paid with a single check for $445 and it must be made payable to the DHS.
