Hi all, I have my visa appointment for B1/B2 soon.

The main purpose of my visit in Business Visit, to meet customers and for training. I have a letter from my company that says so and that they will cover flights, accommodations etc, and that I am not paid salary during this time.

There was an option in DS-160 form to apply for just B1 or just B2 or B1/B2 (for both business and pleasure). I know they generally give just B1/B2, but there are cases where they give just B1 in which you can't travel for pleasure, so I went with B1/B2 and also I would want to travel 3-4 days for tourism after work visit.

1. How do I say this when they ask about my purpose of visit? Do I say that my main purpose of visit is business and that I would travel for tourist purposes for 3-4 days after that? or just say Business? or say Business and Pleasure? or ... ? Will it raise any flags if I say I want to travel for both business and pleasure on the same trip?
2. The letter from my employer doesn’t have a specific date on it for the meeting. Will it be an issue? It was a meeting discussed on teams so no proper form of communication for it, although I know the dates.
3. Will it help my case that I have multiple UK visit visas, including long term, and a Schengen visa and good travel history on it?

Thanks in advance for any help, the whole interview process is stressing me out a bit as it is my first time applying for the US visa. Let me know if anything else I should keep in mind.
