So I’ve been asked to provide flight documents to attach to my DTV application.

I’m hesitant to do so because there’s no guarantee my application will be approved, and I may want to travel a month or so later than the date I originally mentioned.

A few questions:

1. What’s the risk if I arrive a few weeks or even a month later than the date stated in my application? Will this cause any issues with approval or entry?

2. Why isn’t the flight number I found for the same date which I included in the application form not sufficient?

3. Has anyone else received this request before, and how did you handle it if your travel dates weren’t confirmed yet?

4. Do I need to book a return flight?

Thanks in advance for any advice or experiences.
