My passport is to expire in Sep 2017. and My petition is valid till Oct 2018. I have already applied for the passport but it will take another 15 days to get in hand.
I would not want to delay in booking appointment for the VISA Stamping since I will get appointment for 18 days from now. Will that be ok, if I book appointment with OLD passport and take New passport for the stamping? I have heard once you get DS160 confirmation we can not change it again.
