如果移民局没有批准b2 延期,那么在美国过期居住这几个月是否就算非法了?会不会影响到以后?是不是父母想再来美国就进不来了?
-Their illegal stay will be counted from the date their extension application is denied. So, they need to leave US as soon as possible (had better leave US witnin one month from the denial date). But their 10-year B2 visa will be void, so they need to apply for the new B2 visa to come to US in the future.
