I am on H1B expiring on sep 2016 recently married, can my wife apply for b2 visa if I have no plans for h1b extension now? what are the chances of getting the visa?
She should go for H-4 interview and not B-1/2. She will have to disclose your information in DS-160 form, and this could put B-2 approval at risk.
She can apply for H-4, travel on the same and then file H-4 extension along w/ your H-1 extension.
