The problem is that every unscrupulous school and agents in my country claimed to have a license.

If they have a license they shouldn't have any problem obtaining the invitation letter. There's a BIG ? hanging here.

You need to push them. If they can't get you one walk away and find another school. You're not gonna find "Speedy Gonzales or "Road Runner" here in China attending to urgent matters.

Here's one of our Chinese adage ; The search for a doctor begins after our beloved ones are dead and buried proper.

You have to be patient. Well, isn't patient the key to teaching?.

You have to be real careful dealing with schools or agencies. I'm sure you wouldn't want to end up in some sh#tholes in the middle of nowhere.

Trust me Gurl, you are not hearing or reading the above from a foreign teacher but a guy born and raised 100% in China, or should I say a thoroughbred Chinese. Which is correct? "Thoroughbred Chinese" or "Chinese Thoroughbred". Hell, I muddled up.

Good luck Gurl.
