h4 extention supporting documents urgent

[jeyk]

Hi

What are all the supporting documents we need to send to USCIS after filing H4 extension online(eFiling) ? Are the following enough?

1.Copy of 129 approval of H1 holder
2.Copy of I94 of H1 holder
3.Copy of passport H1 holder and H4 holder who is applying for extension.
4.Copy of I94.

Please let me know if I need to send any other document?

Thanks in advance,
J
