A person who has a pending Application to Adjust Status (I-485) is, in general, no longer eligile for any nonimmigrant visa, such as the F-1. However, by being granted advance parole (I-131), such a person may may travel abroad and return to the U.S. without obtaining a visa. The entry is for the purpose of continuing the I-485 application.
