Will I encounter a problem at the immigration counter when entering the US for a 45 day vacation this December if I got my B1/B2 visa via company sponsored training? We applied for the visa last August in time for a scheduled training later that month. We were approved for a 10-year multiple entry visa. But as faith holds it the training got postponed for November, then December and once again tentatively for next year. My aunt would want me to spend Christmas with her then New Year in Canada.
