回复：在线急问xiao bai tu 等有经验的朋友结婚后提交485后我的居留

旅游免签的身份从加拿大入境美国......请问如果我的移民绿卡申请超过我再美滞留的底线6个月

So, you are now Canadian citizen? you are fine. (Marry in Summer? July, or August? and Spouse becomes citizen in July)

Or if use passport from any visa-waived countries, 底线 should be 90 days, not 6 months, and you do have I-94W proving your been inspected.
