Would a British architects drawings be approved in an American city? -

I need to submit drawings for a building permit and I know someone who s married to a British architect. I know they have different code in the UK and I m unsure if he s familiar with US code. Would my local government accept his stamped drawings? Would the fact that he s part of a British firm make it unacceptable?

Every city in the US can have different building codes, so the architect will have to work with the people who are doing the actual construction to modify the building to suit the city, and obtain the permits. A building in the cold north would have different heating and cooling needs from one in the hot south. The soil stability in the area, and the building height would require different foundations. Parking areas, building setbacks, termites in the area, and a thousand other things enter into the equation.
