hi i was previously working in h1 in US and i got my Drivers License valid till 2016 and SSN. i went back to india and quit job and came to US on H4. Can i use the driving license and SSN which i got previously. or do i need to again apply for new Drivers license.
You can continue to use the old DL until it expires.
You can use the same SSN when you become eligible to work again (you cannot work on H-4).
