回复：父母绿卡请大侠指点

想给在国内的父母办绿卡， 是B２签出来办好，还是在国内办好？个有什么利弊？

-If they can get the B2 visa, just come to US and then, apply for the green card after 3 months later. Then, they may get the green card in several months to one year. If they apply for the immigration visa in China, it normally takes one year to two years for the whole procedure.

听说国内直系亲属绿卡也只需要几个月，不知是否属实，如何在官方网站查国内直系亲属绿卡申请速度／进度？
