请教8老师，
我先生人在新加坡（新加坡公民），我是中国籍绿卡持有者，现在想着手通过F2A为他申请绿卡，有个问题想请教：
1. 因为他现在人不在美国，我知道他不用在I-130A上签字。但想问一下，如果在等待期间，他想来美国上学，F签证是否会因为F2A正在process而被影响？
-Probably he may have trouble to get the F-1 visa due to immigrant intent. If he still wants to get F-1, he needs to tell the truth for the F-1 visa application and during the interview, i.e., tell the visa officer that you have filed I-130 for him. By the way, you need to indicate that he will apply for the immigrant visa in Singapore even if he may enter US to file I-485. THus, he can either apply for the immigrant visa in Singapore or file I-485 within US.
Another choice is that he may apply for F-1 visa to enter US first, then you can file I-130 at least 90 days later after he enters US usng F-1 visa.
我的理解是如果已经在美国的话，I-130批了以后就需要走Adjustment of Status，但不在美国的话是在海外申请。担心中间变的话有问题。
2. 我自己有绿卡但需要出国几个月办酒席，这个情况，不会break我的continuous residence吧？
-Not at all as long as you stay outside US less than 180 days continuously.
我今年已经呆够180天了。我在帮他申请绿卡期间出国，对我自己是否有影响？
-No problem.
非常感谢8老师！
