I am a US CPA preparing tax returns for expats in South Korea. Apparently I have licensed an US/Canada license because I cannot change the business address as you instructed. I have a business license registered with the Korean Authorities. I am in process of getting PTIN and e-filing right now and want to acquainted with the software before I am fully set up. May I have an instruction to update my license so that I can prepare taxes for expats in Korea? Please kindly send me the instructions on how to update or change license asap. 

Thanks
