You're moving to America. We handle the visa, the company and the taxes.

Moving to the USA is a life decision, and it has a legal side: the visa that fits you, the company behind it, the bank account, the taxes here and at home. Sebastian Sauerborn made the move himself, from London to America in 2008, and now guides entrepreneurs and families from Europe as they cross the border.

Here are our guides to moving: where to, when, what it costs and what you need to sort out at home.
