Hello everyone! I have a question...so I was born in Russia with korean ancestory (I am ethnically korean). I was born in Russia but grew up most of my life in the UK. Therefore I have 2 passports. I would like to know if it's possible to enter korea without a visa so free 90 day stay and obtain the F4 visa inside the country. I have tried to do this already with my Russian passport with a lawyer here but ended up getting scammed. All the help and advice would be appreciated.
