My wife has recently got her H1B Visa stamping done from India. However her current employer has not allocated any projects till now. She is planning to be on LOA for sometime and travel US on H4 Visa.
We have following concerns
At the time of H4 Visa interview, will the officer cancel / invalidate her already stamped H1B visa.
If her employer finds a project does she need to travel back India and come back US on H1B or can the employer apply for COS from H4 to H1B
Does her H1B petition comes in risk if we apply for H4 Visa.
