I just checked your account and I can see that you were able to successfully add your address with Japan as a country. If further help is needed let me know, thank you.
When I signed up for upwork, I never completed my account. Now I signed in after a while, and I was asked to fill the required information. I cannot change my country, however. It is stuck with the US. I live in Canada, and hence I cannot enter my address for profile completion. How can I change the country to Canada?
