You do not have to be in the UK & USA — or travel to the UK & USA — to set up a limited company in the UK or USA. The one thing that you will need to have is a registered UK & USA office address. While we would recommend a registered office address, you can use a residential address to register your company.
We provide international company formations packages help you set up your business as a non-UK & non-USA resident and include a registered office address.
