Could anyone tell me if they have had any problems with purchasing a one way ticket when going over on a years work permit (hopefully longer) with the immigration at the airport etc. If so what are the alternatives? Thanks

We recently did just that, the airline you book with need to know you have the correct documents, before they can issue a one way ticket.

At the airport they also wanted proof, we just showed them the Employment authorisation letter, the one you show immigration to get the actual permit.

You should have no problems ... if you have the correct documents.

Good luck
