For applicants who require an early offer of admission or those with visa and passport restrictions*, their applications must be submitted at least 3 months before the above deadlines. *In case of incoming students from Afghanistan, Bangladesh, Cambodia, China, Mongolia, Pakistan, Philippines, Sri Lanka, Vietnam, Middle and Central Asia Countries, and some African countries, the visa authorization letter will be issued by the Ministry of Foreign Affairs (MOFA) of Thailand, not by AIT, and dispatched to the respective Royal Thai Embassy or Consulate via the diplomatic channel. The visa authorization will normally be approved 2-3 weeks after issuance of the Certificate of Admission.
