after getting family based green card as a parent of citizen _ URGENT

[s natarajan]

After getting green card by AOS, should we necessarily go personally only to Social Security office near to the address given for green card to apply for SSN? Is it good to apply in another state where we shall be visiting?

The official policy is that you can go to any office for service https://secure.ssa.gov/apps10/poms.nsf/lnx/0200904064 see section D

That said, apparently some offices give "nonresidents" a hard time
