I currently live in the Netherlands and have a small freelance web design business I formed through the KVK office. Most of my customers are in the United States and I would like to continue to grow my business in the United States while working remotely here in the Netherlands. I would like to rent a small office location in Phoenix, Arizona so I can get more customers in that area (rather than locally here in NL). Is that okay for me to do? Are their tax issues or rules against me having an office in the United States for visibility and doing business from here?
