My name is [REDACTED] and I am the CFO for [REDACTED], a UK firm that has offices in NY and Chicago. I recently attempted to enter the US for business purpoes through the visa waiver program but was denied entry. I explained that the purpose of my entry was to review accounting procedures at our newly opened branch office in Chicago. Immigration told me that they considered this work and that that was not authorized under this program and that I should apply for a work visa. Is this new policy? I have never had trouble with this before.
I have seen this type of issue before and I have made it a point to be available for my clients who enter through O’Hare in case they run into entry problems like yours. If you had called me at the time of your entry I may have been able to sort this out with CBP at O’Hare but since you’ve already left it is too late. This is not new policy but just a misunderstanding of current policy. You may use the visa waiver program and the B1 visa for limited business purposes.
