I am from germany and an employee of a large US-based IT company. I recently applied for a B1/B2 and I went through the whole process. I then went to the consulate last week and they accepted my application and told me that they would ship my passport to me as I ordered. I just received my passport via the mail but when I checked everything, I noticed that instead of B1/B2 the visa only states B1. Is this just a human error or is there more to it? And most importantly, is there anything I can/should do about this to change it to a B1/B2 and how long would this take?
This answer is helpful, let me repost the relevant parts.
You do not need to apply to change your nonimmigrant status if you were admitted into the United States for business reasons (B-1 visa category ) and you wish to remain in the United States for pleasure before your authorized stay expires.
The only situation in which you need a B-1/B-2 visa specifically is if you want to use the same visa for different trips, of which some are business and other are purely tourism.
