They don't give cards, they take points. And you can get one taken pretty fast if you throw a lot of nut shots. If you mean getting your book so you can fight, idk, it depends on where you're from. Over here I got mine like 2 weeks after I sent in the paperwork. Could be different in the UK though. Ask your coach.
in the uk it doesnt take long, get ur medical done by a doctoer then send the form away to the governing body should be there 1-2 weeks
