Part of the process of getting a work visa to teach English as a second language in Korea involves a medical check. Before they issue you a visa they measure your chest size, foot size, test your eye site, and then they do a blood test for STDs. Yes, they measure your chest size as part of the teacher visa process. I was tested for diseases back in Canada before I came over to save myself the trouble of having to head home if I was positive for anything. Not sure how I’m still negative for everything, considering the numbers involved, but I guess I’ll just thank my lucky stars.
