I have recently recieved a job offer in lenzburg.
what do i have to do to get residency and work permits and am i able to get all this before i go out there.

as a uk citizen your entitled to them automatically, you have to get here first, stroll along to the town hall, give them a copy of your work contract etc, sign some forms, pay a fee and that's it

within 14 days of getting here iirc

As a Scot, you are EU and need visit the City Council of Lenzburg with your passport, employment agreement and rental agreement, a formality basically and the permit will take anywhere between 2 weeks to 2 months to be issued ( but you are allowed to work and live the moment you arrive - best to register with the City Council within 8 days of arrival ).

Thanks very much guys this is what i thought but just stressing out and had to make sure thanks again.

the swiss make paying fee's simple
