Welcome to the Uk Mickaela,
Yeah its really freezing here na, freeze our puwet lol.
You can either phone them up or go to the office. In my experience I phone them up and they sent me an application form (the requirements that they needed are stated on the form) then I sent it back to them after filling up using the envelope that they provide in the pack. After 2 days I received a letter from them stating my national insurance number and telling me that my card will be sent 6 to 8 weeks. And yeah I did receive mine around 6 weeks after my application.
hope that helps a bit![]()
