I applied for a B2 visa. My visa was stamped B1/B2. I travelled to the US a few times using my visa as a visitor. My company wanted to send me to the US on a business trip. Can I travel to US for a business trip with my visa? Will I face any problems at the port of entry?
According to the US consulate:
In other words, as your visa is B1/B2, it allows you to visit the USA for both business and pleasure, however note that
That is, you can go on a business trip, but you are not allowed to work in the USA as a permanent employment location.
Here's a link to the US consulate in India, but the rules are the same in other countries.
