What are the tips for getting a visa approval when documentation is lacking?

I successfully completed the visa application with Seoul Embassy (very strict)

We applied for soft power category and they asked us a lot of documents that we didn’t have it like a tax document from own country (my gf worked in foreign countries for 3 years)

So I decided to write letter to explain everything about the situation and our plan to make the financial stable,

I got approved after submit additional documents in 3 days, so happy.

So if you have any questions and your intentions to come here is not dirty😂 you can ask me any questions if you would like to
