I have got H4 to H1B approved, but COS is not approved due to some queries.
Now I need to travel to India to get the Visa stamped, but I have below queries:
1. How much time i have before I must appear for visa interview? what will be the impact if I appear for interview after couple of months.
2. If the H1B is rejected in interview what will be the status of H4? will there be any impact?
3. Can I travel to Canada to get the visa stamp?
Please help me with these queries.
