At the naturalization ceremony (2/13), we received instructions on what to do next.
(1) apply for and get passport (for ID).
(2) visit Social Security Office to update status.
(3) Voter registration.
So I just did those. Took about 5 weeks.
(I) applied for passport on 2/15 ($165). For the application I needed to give them the Naturalization certificate (which was mailed back on 3/11). There was a time window that I could not do other paperwork until I got either passport or the certificate.
Received passport on 3/8. I did not ask for expedited processing, so getting passport in 4 weeks and one day was not bad. They originally estimated 6-8 week processing time.
(II) With passport in my hands, I visited Social Security Office on 3/12 to get SSN card after status update. Took about 30 minutes (25min wait, 5min at the window). I got SSN card in 6 days on 3/18 (today). Not bad at all.
(III) Since I have my passport, I used it to renew my Drivers License with Real ID update (3/18 today, $77 for 8 years). Real ID will be handy to fly or to visit federal government facilities. At the same time, voter registration was done.
I should be getting the Real ID DL and voter registration card soon. All so legally with some fees.
Small things here and there. Collecting cards.
