H4 Visa validity after employer change

USA H4 Visa
#1

Hi, Can someone help me to answer following question for H4 visa stamping ?
My case is, last year I travelled to India and got H4 visa stamped till 2023 on the basis of my spouse employer as petitioner working for client A but recently my spouse been hired directly by client A as FullTime so is my visa still valid in this case ?

Is your prior H4 visa (spouse/child of a temporary occupation, temporary worker or trainee applicant) still valid?

Visa only serves the sole purpose of entry to the US so even if your spouse changed the job, your visa is still valid for reentry till its expiry date. When you enter using the current visa, you will need to carry the copy of current I797 of your spouse from client A.
