我和老婆去年結婚，她家在中國有個八竿子打不著的親戚辦親屬移民，她背著我做了擔保人，提供了去年她自己的tax return （去年我們file tax return時， status還都是single，今年準備第一次file married jointly),我不清楚這個擔保人具體需要承擔多少責任，如果我們今年一起file tax return（married jointly)，
我是否有連帶責任（雖然我沒有在擔保表格上簽字，我是否會成為連帶擔保人？）- She takes care of her relative financially, and you take care of her.
明年初我的臨時綠卡就要轉正了，是否一定要提供married jointly的return？ married seperately的行不行？- required but don't see it gets denied definitely when filing separate
老婆給他人提供擔保一事是否對我綠卡轉正有影響？ - None as she is financially capable for 2 beneficiaries
請大家幫忙。謝謝了。
