H4 with Valid visa travel back to US /Any restriction?

Hi Kumar,

Moved to company B and got approved H1 & H4 stamped in India on 2019 valid until dec’21, my wife stayed back for few month and could not come due to Covid situations. She wants to return now however same company filed H1 & H4 amendment and extension due to change in job location on Sept’2020. New H1 got approved with Normal processing but H4 still shows application received. In this scenario

1)Can H4 enter US with the Stamped valid visa on her passport?
2)Documents she need to carry with her and what question she may expect in the port entry?
