I have a currently valid "B1 in lieu of H1B" visa, which I previously used to enter the US for a temporary business assignment. To be specific, the class is B1, and the annotation is "B-1 IN LIEU of H, PER 9 FAM 402.2-5(F)".
I wish to travel to the US for tourism purposes. Is this visa valid for a non-business trip? There are plenty of answers that say this is possible with a B1/B2 visa, but I was unable to find anything about using a B1 or a "B1 in lieu of H1B" for a tourism visit.
