Hi all, quick question. I am on a NON-O based on marriage, my visa expires in June 2020, and my current 90 day permitted to stay expires in May. I want to convert to an extension of stay based on marriage (i have all of the requirements), but would like to know the minimum time i can apply before the end of my visa, and if its possible to do before my permission of stay (entry stamp) expires.
