Interview reschedule flexibility from H4 to L1B

[kedar_89]

Hello!

I am scheduled to get married in July in India (I am on H1-B visa) and my wife will be requiring an H-4. We were planning to schedule her H-4 interview appointment on July 18th or July 19th.

However, we are learning she could find a work opportunity in the US and will be required to file an L1-B visa.

My question - Say we fill out DS-160 and have a confirmed appointment for H-4 visa. I only learn later that her employer wants to move ahead and file for L1-B. Is she allowed to submit a new DS-160 (for L1-B visa category) and retain the same appointment date?

Or would she have to cancel the existing appointment and re-submit DS-160 and book a fresh appointment for L1-B?

Has anyone cancelled/rescheduled appointments and gone for a different visa category after reschedule? 

Thank you!
