http://www.visajourney.com/forums/index.ph...om&page=k1k3aosi can tell you the way i did it so far
1.- about 2 weeks after arriving to USA i applied for my SSN i presented my passport with k1 visa and my birth certificate and translation, i was already in system so i got it. it arrived a week after by mail.
after marriage......
1- Since i told the minister i needed my marriage certificate and told him please to send it fast, and he did it!!, 4 days after the wedding i had my marriage certificate to continue with process. THIS IS IMPORTANT THIS USUALLY TAKES WEEKS, ASK YOUR MINISTER!!
2.- i applied for drivers licence, every state has its own rules i live in massachusetts and it was very simple since they honor drivers licence from mexico, i had one so i didnt need any test, just documents. i got it by mail 10 days after application. NOTE: i waited to get it after marriage to get it with my new name.
3.- i went back to change my name at SS only needed old card, passport and marriage certificate. i got new one by mail a week after.
4.- i got all my documents according to the guide here, and applied for AOS and EAD i didnt apply for advance parole i dont need to leave the country for now.
i sent AOS and EAD together in same package with separete money orders to chicago, $395 for AOS (iincluding biometrics) and $180 for EAD
thats all i got so far, hope it helps u and if you have more questions please ask..........
good luck
