The country on your account defaults to the country where you have created your account for the first time. This is fine if you create an account and schedule your appointment in the same country. The system also uses the name, date of birth and passport number to look up any duplicate accounts. So, if you create a new account, the system will flag it and will ask you to merge. If you need to change the country on your account or merge your new account with the old one, you must contact USTravelDocs customer service. They have the ability to change the default country on your profile or merge your old account with the new one. Their customer service is very helpful in fixing such issues.
