i am working on L1 and i am going to get married in next Feb. so i have question regarding that.
1. is it required to add my wife's name in my passport, or my name in her passport for applying L2?
2. is required to change her last name(make it same as mine), in marriage certificate/passport or some other document?
3. how much it takes for getting L2 visa?
4. after marriage i will be coming to US and my wife will be in india, and she will be doing all the fomalities, is there anything i need to take care?
Please help.
Thanks in advance for the help.
