一個朋友六年前用別人的護照入境美國，
-Your friend will be considered to enter US illegallly(USCIS will find the truth/fraud if he/she apply for GC) and thus, he/she will never get the green card based on the current immigration law even if he/she marrys a US citizen. I can not see any possibility for your friend to get the GC based on my own knowlegde.
現在想和一個老外結婚，請問：
1.她用自己的護照登記結婚，會不會有什麽麻煩？
2.如果結婚後馬上申請綠卡，用什麽途徑申請最好
