Your intent is clear but the wording needs more polish since you were an English major.  No matter, the more you write the better you will become.  If you wish me to correct your essays, just send me the link of that essay.

During my days as a university student, I majored in English language and literature. So, I can read and understand what is written in English but not good at writing and speaking English.
So, now I' trying to get a certification for teaching Korean to foreigners. It is kind of depends on a Korean national approval certification. If I get that certification, I can get a job overseas because the Korea government guarantees me who can afford to teach Korean.

For the part in red I can'texactly tell what you are trying to say. Are you trying to say that the Korean government guarantees you that they will help you to pay to teach Korean? Or are you trying to say that you have to be able to afford to teach Korean in order to get the certification? From the way the sentence is written, it sounds like you are saying that the Korean government guarantees you a list of people who can teach Korean.  

But before that, I need to improve my English writing and speaking at least. 

for the part in blue, in order for it to agree with the rest of the text, it should be written "But before that, I need to improve my ability to write and speak English."
