Folks - Below is a brief on our activation trip . We hope the given timelines will prove useful.
We arrived on August 21st (Friday) with POE at JFK . We entered via the US Citizen's line. When our turn at the immigration officer came up, we handed over our packet and passport . After opening our packets, he quickly took our finger prints, took digital pictures , stamped our passports and said we re all set . All of this was done in under 5 minutes !
On Monday 23rd August, we paid a visit to the Social Security Office to ensure our SS ID process was in place. The kind lady at the counter informed that since we had already requested it while we did our DS-260, there is no need to come here. If we don't receive it in 2 weeks, just come back. 5 days later the SS cards were in the mail.
On Tuesday 24th, we went to the bank. I already had an account created ( from several years ago) . So it was a matter of getting a new debit card. Based on the feedback from the forum and to start building a credit history , I applied for a secured credit card. I was approved and received the credit card 9 days later in the mail.
The following Tuesday, after receiving the social security number, I went to obtain my drivers permit and cleared the written test. Since I had my license from my country , I produced that as well and luckily they waived the road test . Consequently walked out with license in hand.
A few days later we exited the US and waited for the green card to arrive. Exactly one month after our arrival at POE, the gc arrived at the mailing address .
It was a fairly straightforward process overall .
