Say hello.
Spotted a number that is out of date? Want a tool that does not exist yet? Running a service for foreigners in Korea and want to talk? We read everything.
We usually reply within two working days, Seoul time (KST, UTC+9).
Before you write
If a tool gave you a strange result, include what you typed and what you expected. For visa or tax questions, remember that we build calculators, not legal advice. Immigration (1345) and the National Tax Service (126) have English lines.
