As I know, the immigration officer at POE will take my brown envelope, which is used for applying greencard and SSN. During this period, I need to stay put and wait for SSN and greencard at home. Some take few weeks but some take months to receive them. I can wait for greencard but can't wait for SSN to come very late. Many people advised me to go to Social Security Department directly after entry. Here are my questions;
1. Should I wait for SSN or should I go to Social Department right away when I get there?
2.What would happen if I use my previous Tax ID during waiting for SSN? any penalty?
3.If I go to Social Department to apply for SSN by myself, will there be any conflict with the one submitted by the immigration officer through the brown envelope at POE? any penalty?
4.From Q3, if I accidently get 2 SSN, which one should I use? the one I apply by myselt or the one through the brown envelope?
5.Is it likely that my SSN will be the same number as my previous tax ID?
