I have never been to the United States before. I have a relative who's been living there for long time.
I decided to travel to the US and just got a US tourist Visa (B2) authorized which is valid for 5 years. Now, my plans have changed, so will have to visit the US not sooner than next year (7-8 months later).
I heard some rumors that "if you don't travel soon enough, the visa might lose its validity." Is this true? I wanted to hear from people who are familiar with the situation; please advise.
