H4 to H1 & Transfer

Dear Experts,

My wife came as a dependent(H4) in Feb 2014. We applied for her H1B this year and it got picked in the lottery and approved. From October her H4 status will change to H1.
She is getting job requirements for direct position from few companies. Can she apply for those companies ? Is she eligible to work for a different employer if they are ready to apply for H1 transfer?

Need your valuable suggestions on this

Yes, you can transfer visa immediately after approval. But not suggested. Sometimes query can be on the candidate and may ask for the reason leaving the current employement. Hence, it is advised to have atleast 3 to 4 pay stubs from current employer before you plan to move to new employer.
