H1(primary) job change before H4(dependent) travels to US



Would really appreciate if someone has any pointers on this.

H1 beneficiary - approved - In US
H4 dependent - approved - In India

what are the implications of job change for primary(H1 transfer) before H4 travels to US? Should the dependent apply for a fresh H4 in order to be able to travel?

H4 can simply carry the copy of the new H1B approval along with other documents and use existing valid visa to travel to the US.
