我明天海龜回國，今天收到Eb1a I_140 approval 的信。我先生想申請F1visa明年秋季入學，我想在國內申請移民簽證，請問這兩者有衝突嗎？
-No unless your file I-824 for your spouse to apply for the immigration visa with you. By the way, if you have selected Part 4. 1.b. of the I-140 that you will file I-485, application for Adjustment of Status within US, you need to file I-824 so that USCIS and NVC can process your paperwork for you and your kid to apply for the immigration visa in China. Otherwise, if you have selected Part 4. 1.a., then you do not do anything and USCIS and NVC will automatically process your paperwork for you and your kid to apply for the immigraiton vis ain China.
有人說，讓我先生先持F1 visa 入境，我和小孩申請移民簽證（因為移民簽證要等大概一年），我們進入美國拿到綠卡後，再給我先生file485. 請問這樣可行嗎？
-Yes.
還有其它更保險的方法嗎？我拿到綠卡後替我先生申請485要排期嗎？
-Yes, but EB1A 排期 is always current in these days, so he can file I-485 immediately after you enter US using immigration visa.
是否也是大概半年左右就可拿到綠卡？非常感謝您的答疑解惑。不好意思在節日期間打擾您了。我明天回國後就不容易上文學城向大家請教，跟大家分享了:(. 祝大家心想事成！
