Hello Peter, I'm a non-resident and non-citizen selling consultancy and development services to U.S. companies (as a contractor, filing a W8-BEN). I hold a B1/B2 visa (only used for conferences and training so far).

Are there any potential immigration issues if I do U.S. based work for a couple of months on my B1/B2 visa? Could I do that more than once in a year or would that be a red flag for immigration services?

I don't want to move to the U.S. but I do want to be able to work onsite during crunch times, pushes to production or similar events, without risking my visa.

I also want to allay fears of potential customers that I don't qualify as an employee, but that's not an immigration question I guess :)

Thank you for taking your time for answering!
