I just went to Chinese embassy get a tourist visa
so once in China I could get a job as a teacher.
(I don't have a certificate though). The lady told me
that I could not get a work visa once in China,
even if some school hire me. I would have to leave
china and apply from outside with the school sending
the paperwork to the proper authorities. I didn't
know it was such a hassle to teach in china.
I'm in Laos right now. I'm from USA.
Is it really that hard to get work visa or permit?
Does anybody have any personal experience in this?

Many thanks. Paul
