最近很倒黴,XIaobaitu or

最近很倒黴， 明明是phd program 第三年。 F1卻不小心expired( I20 , I forgot to extend , but who the gave me the three -year to start with anyway?)。 剛遞交了EAD （ family based 485 去年 Nov.遞交的），但是九月 開學的late registration 恐怕都來不及了吧。

WHAT SHOULD I DO ?
1. to get legally registered for school, should I do anything else? or just show them my AOS status( 485 receipt)?
