H1 to H4 transfer docs

[r_gopal]

Hi, I am on H1 presently, but I want to transfer it to H4 as I am not going to work anymore. Can anyone tell me what all documents I need to do this transfer? Do I have to go thru an attorney or can I myself file it?

Iam also intrested to know about the docs required for COS from H1 to H4.
