Documents required for F1 to H4

[Kanupriya Dhiman]

Hi

I came to US on H4 and applied for my COS from H4 to F1 last year. In this process, my previous H4 got expired by more than a year now and I would like to go to India and come back on H4 to apply for H4 EAD.
1. Do I need to carry the F1 documents justifying my visa status till this time?
2. Will they scrutinize more in this case about my changing of status again?

Any comment in this regard would be appreciated.

Thanks
