回复：请问在纽约以基于公民婚姻申请绿卡，历时多久能拿到绿卡呢

depends on where you are. i submitted application last august in Philadelphia. on the receipt notice, it says 10 months. when i checked with them last months, i was told 15 months starting my application date; if still no decision, another three months... my understanding is, keep waiting until they notify you - their promise doesn't count!
