I'm finishing my College and after that my intention is to ask for PGPW. Currently, I'm a part time IT consultant
Anybody knows if it's possible to my wife still working even I'm an IT consultant?
Are you working for one specific company on a contract? Will they be moving you to a full time contract once you have finished school? Can they provide you with an employment letter confirming that you are working for them on a contract?
Then you should be OK. I would wait until you are working full time and can provide three pay slips to prove it before you apply for the open work permit.
