回複：在線急問xiao bai tu 等有經驗的朋友結婚後提交485後我的居留

旅遊免簽的身份從加拿大入境美國......請問如果我的移民綠卡申請超過我再美滯留的底線6個月

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, 底線 should be 90 days, not 6 months, and you do have I-94W proving your been inspected.
