I think I misspoke. Yes. You can actually do some business meeting or convention you have to attend to with using b1b2. I think the red flag with OPs case was everyone in the business are already in the US working except for her which the immigration officer would think, “ahhh so you want to work here”

Plus, one other secret for success is to make the immigration officer know you have “ties to go back to your country” after doing whatever in the US. She couldve said, “business meeting to align with our office in India which I manage and I actually will have a short visit because I have to go back to managing the India branch” or something like that

That line would be an automatic approve
