我明年初绿卡及即将满5年，想入籍后立即给父母办绿卡。我的父母过去几年来美多次，出入境记录良好。现在因为种种原因，希望一直能留到明年绿卡办好（或者 有了AP）再离境。可能中间也就几个月gap。听说过周围几家父母由黑洗白都没有问题，但也听说移民政策近年来愈发趋紧，
想请各位老师证实，如果有几个月 的gap申请绿卡会有问题么？
-No problem. The only issue is that if there is any accident related to them (e.g. car accident) that the police is involved to find that they illegally stay, that will be a problem. Of course, the possibility for this kind of thing is very small and thus, you do not need to worry about it, but just be careful a little bit.
