Why don't you apply and tell us all about?

Don't ask people on here.....just go and find out for yourself from the school you want to work at. Thats the only way you can really know. Tell them your credentials and situation and see if they want you. 

Most schools cant hire foreigners anyway....so no matter what you would be working illegally. And if you're not from an English speaking country then the puck stops there...you need to be from an English speaking country. So tefl or not...your most likely cant teach. And if that is all you need...you can get one in an afternoon online.

No.

Next.

Before yes, but now no as its a new requirement thats loaded to a website that would grant you a Working Permit Card, if they don't see it, you are getting it.
