Forgery of the test result notification letter is a crime.
No matter how realistically and artificially fabricated the test results are, the system provided by the OTAFF to the Immigration and Entry-Exit Administration will immediately identify them during the agency’s inspection.
Whether the test was done by yourself or by a third party, if you falsify the test results, you will be banned from taking any exams with the OTAFF, both domestically and internationally, for five years.
