我去年给父母申请绿卡，他们没等到就拿了AP回国去了。前几个月我父亲的绿卡批下来了。但现在我母亲的要求面试。国内情况有变化， 他们又不打算要绿卡。 一两年之内他们不打算来美。 他们以后如还想来美的话， 这对他们申情签证有影响吗？
-Your mother had better write a letter to USCIS to request withdraw the I-485, thus the I-485 denial notice will list the denial reason: the I-485 was abandoned. Thus, it is very useful for her future B-2 visa application.
我父亲也需要签证吗？
-If he wants to keep the green card valid, he needs to enter US using the green card, and apply for the reentry permit to stay in China for > one year < two years. Otherwise, he may just abandon the green card in the US Consulate in China, and apply for B-2 visa to enter US.
谢谢！
