How do you transfer from Costco UK to Costco California?

If you go on the employee intranet at work and look for job openings there should be a thing in there that says international, and its for international transfers. I also believe there's a phone number you can contact, and they should be able to help you. Other than that its making sure you have the correct paperwork in order to transfer, (a passport), and putting in a transfer request (and hoping it gets accepted). Im not for sure what the 1800 # is so it might be something your personnel/payroll clerk could look into for you (they could probably get it for you) thats part of their job. After calling the number they should tell you what paperwork is needed in order to make an international transfer.
