You do not need to create another profile if it is also serviced by CGI. You can simply contact us through the Contact Us section on this website and share your passport number, UID or email address so we can retrieve and update your profile with the new country where you plan to apply for your US Visa. If you are applying in a country that is not covered by CGI, you will be invited to create a new profile. As a reminder, MRV fee receipts paid in one country are non-transferable to the other country.
To travel to the US visa-free, you must have valid ESTA authorization. Once granted, ESTA is usually valid for a period of two years from the date of issuance. During this time, you can make mutiple trips to the US, provided you remain ESTA-eligibile and provided you reason for travel is permissible under the visa waiver program. If your passport expires prior to the two-year point, your ESTA status will no longer be valid.
Some countries apply the principle of reciprocity in their visa policy. A country's visa policy is called 'reciprocal' if it imposes visa requirement against citizens of all the countries that impose visa requirements against its own citizens. The opposite is rarely true: a country rarely lifts visa requirements against citizens of all the countries that also lift visa requirements against its own citizens, unless a prior bilateral agreement has been made.
The Democratic People's Republic of Korea (North Korea) requires that its citizens obtain an exit visa stating the traveller's destination country and time to be spent abroad before leaving the country. Additionally, North Korean authorities also require North Korean citizens obtain a re-entry visa from a North Korean embassy or North Korean mission abroad before being allowed back into North Korea.
