Company filed H1B visa for me. After that I got married and now planning to send to U.S.. What about the process of dependent visa can any one explain this is 1st time I am to U.S.
1) What are the precautions I need to take?
2) For dependent how much percentage they will deduct as tax?

How to apply for a dependent visa is actually a LEGAL question best posted in the LAW forum under Immigration Law.

Not sure what information you want for the dependent tax.
