I was told that you need to get Advance Parole if you want to leave the US during your green card application, because if you leave the US without it your i-485 application will be considered abandoned. So I was wondering when during the green card application progress can you apply for Advance Parole? Is it after the completion of the biometrics appointment? Has anyone applied for AP before? What is the process like and how long did it take? ps. I'm currently on H4 status, if that makes a difference. Thanks you advance.
