Konnichiwa minna san!

Just a quick question and hoping to get an answer.

I am a undergraduate of BS course (i wasn't able to finish my thesis, that's the reason). I have a permanent residence visa, N3 JLPT certificate and planning to get a TESOL.

Heres the question:

Do I have a chance to teach English? Am I qualified? If I'm not, what else should i need to do?

Thanks in advance!
