I have a OA visa which expired on 14 Jan, i am now on the entry stamp until 10 October, i intend to leave Thailand to Australia in June, while in Aus i will obtain a new passport as my current one expires same day as my enter to stamp 10 October, i know i need a reentry permit before departing if i intend to come back on the original entry stamp. The question is while i am in Aus if i reapply for a new OA Visa, do i have to cancel the current rentry stamp.
