The current estimated processing time for applications from India is 35 days. As this is only an average processing time, actual processing could take much longer.
If you get passport submission requests when you're in the US, you can submit your passports to the NY/LA VAC for visa stamping. You'll need to factor in at least 8-12 days for the processed passports to be returned to you
I recommend you submit letters requesting for the passports to be returned to you. You must clearly state that you are NOT withdrawing/cancelling your TRV applications.... and that you will re-submit the passports whenever the visa office needs them to make final decisions. Do include your flight tickets.
You can submit these letters to VAC Mumbai + email the Bangalore consulate as well. I suggest you do this ASAP as there are several holidays (including Diwali) shortly
