When a Form I-131 is approved, Advance Parole (AP) is normally granted for multiple entries into the U.S. and for the time period required to complete the adjustment of status application, not to exceed one year. However, this is not set out in the law anywhere. It is a USCIS policy.Therefore, you could stay out of the U.S. for up to a year, making sure to return before the expiration date on your document.Now, for the important informationu2022 Be careful about what you might miss while youu2019re away. USCIS will call you in for a biometrics appointment (fingerprint and photo) within a few months after you submit the adjustment of status application as part of your advanced parole application. In addition, you are required to have an interview at a local USCIS office. The exact timing of the interview depends on how backed up with other applications the office is.If you miss one of these appointments without asking for a postponement, you could put your entire application at risk. And even postponing such appointments can delay the process by a long time.I write free information and articles on the US fiancu00e9 and spouse visa processes on my website and blog.
