dependent visa required

[Honeq]

Hello,

At the time of applying for H1B I did n't get married but I got married recently and got the h1b too.

May I know how to apply for dependent visa
1. should I ask my employer to take care of that?
2.what is the dependent visa (h4) cost?
3. how much time it will take if I start applying for that now?
4. Is there any premium processing fee?

please let me know the details or provide me some links.

thanks,
venkat.
