H1 --> H4 visa stamping

Hi all,

NEED HELP!

Please advise on the following:

Me and my wife were on H1B from our respective companies. My wife had to travel to India in Nov’17 for some personal reasons. She had her payrolls run till Oct’17. She is still in India(since last 4 months). Her employer said that there is no project currently for her. So we are planning for her H4. She will be going for H4 interview in two weeks time. Can you please let me know apart from my documents does she need to carry any documents from her previous H1B status? If yes, can you please let me know what all documents should she carry?

Thank you all for all the help!
