Which of the following forms is specifically for the application for a travel document?

Form I-131 is specifically used for applying for a travel document. There are several types of travel documents that can be requested through this form, including re-entry permits, refugee travel documents, and advance parole documents for individuals who need to leave the United States temporarily while their application for adjustment of status is pending. The purpose of Form I-131 is to ensure that applicants can travel outside the U.S. without jeopardizing their current immigration status or future eligibility for residency or other immigration benefits.

Other forms listed serve different purposes within the immigration process. For instance, Form I-765 is used to apply for work authorization, while Form I-512 is related to advance parole and does not serve as a standalone application for travel documents. Form I-140 is an employment-based immigrant petition and is not used for travel purposes. Therefore, the specificity of Form I-131 in relation to travel documents makes it the correct choice for this question.
