Work permits are tied to your job. Find a job and then they will give you papers to get the work permit from the government. Or at least this is how it went with me :)
Not officially but there are ways around it (agents) But if you need it before the 26th then you are already too late. Need about 4-5 weeks for the paperwork. If anyone says they can do it quicker then it is likely a scam.
I didn't ask that question to the hotline. I only asked about Ed as that is the only one i'm really interested in. The Immigration office funnily enough told me I could switch to and Elite visa.
