Sorry, you have not qualified for Non-immigriant visa under section 214(b). Hands over a paper with
details to section and law details. If you wish you may apply again sometime later. Thank you.

Queries:
1. What is your view on my interview, why do you think I would have been rejected B1 visa?
2. What does section 214(b) actually mean? Shall I re-apply and by when?
3. What should I change in my DS-160
3. Can I re-apply for B2 Visa for tourist purpose and will B1 Visa rejection have any impact?
4. If in future I plan to visit USA for Business purpose can I use my B2 visa or will I have to
   re-apply for B1 visa?
5. I planning to apply for Schengen Visa, just to avoid rejection for 1st time Visa applier for
   Foreign country? Do you have any thoughts?
   I plan to ONLY apply for visit and not taking any visit for Europe.

Looking for replies and suggestion from this forum.

Thanks in advance!
