回複：如何替我妻子辦綠卡

各位專家，老師，我最近剛拿到綠卡，我妻子現在在加拿大，請問替我妻子申請綠卡的步驟是怎樣的？我是否先要先替她申請 immigrant visa petition，等得到批準後她再在加拿大申請 immigrant visa，
-Correct.

之後進入美國後再遞交 I－485？
-Not need if she will get the immigration visa in Canada. If she choose to enter US as a visitor and then file I-485, she has to enter US before you file I-130. Then, she has to keep her status valid until the priority date to be current to file I-485. So, you have to think how she can keep her status for such a long time.

因為她拿有加拿大護照，可做為visitor直接進入美國，請問她可以先呆在美國，然後再申請簽證嗎？
-After you file the I-130, she may not be allowed to enter US as a visitor due to her immigration intent.

謝謝您的谘詢和幫助
