I am a greencard holder and applied for reentry permit because I need to go overseas for medical reason. I left before the biometric appointment because my condition could not wait. By missing the biometric appointment I know my reentry permit application was probably denied. My question is: would i be able to come back to US again using my greencard, if I've been out of the country for less than a year? and, does a denied/abandoned reentry permit application post a red flag in my record?
