These are things you needed to after landing in U.S.A
1)Buy prepaid sim so that you can make phones call,to get prepaid sim you really don’t need any thing like id proof or any thing like in India.
check out this carrier http://www.lycamobile.us/en/29-international-cellphone-plan
2)Install Google Maps for navigation, set the address and go.
Here no one helps in navigation because this country so big to remember any thing.
3)Install Uber application in mobile to book cab,if you lost just book cab from mobile using Uber app.I personally felt very comfortable with Uber app.
4)Figure out public transport in the place you are going to live just google it.Cabs are expensive public transport is cheap but you should know the routes.
5)Apply for SSN this is the fist thing to do if you are here on H1B/L1 Visa.
documents needed to apply SSN https://www.socialsecurity.gov/ssnumber/ss5doc.htm
6)Apply for driving license,you can drive here with India license for couple months but better to apply Learners permit as soon you landed here so that slowly you can get valid driving license.
7)Find nearest Indian grocery store just google it.
8)More importantly Google it for anything before you start doing.
finally Grab beer:)
