Currently my wife is in India and has valid H1 petition in approved status. But currently her employer is taking time change her LCA details, due to change in organizational policy. This may take her close another 3 months. Currently she would like to travel On h4. I've following questions: 1>If she travels in H4 will H1 still be valid? 2>if she returns to India, can she get her Visa stamped from her own employer for H1 ? 3>If she finds a job while she is in US can she change her employer and use the existing petition? 4>if she find a job while she is US what is process for COS? Can there be RFE while changing Employer? Thanks!
