A classic visa for Thailand is a traditional visa that must be obtained in person from a Thai embassy or consulate. Applicants must complete an application form, provide required documents such as their valid passport, photo ID, return ticket and proof of stay in Thailand, as well as pay the corresponding visa fee. The application process can take several days or weeks, and the visa is usually stamped in the applicant's passport.
An electronic visa (e-Visa) for Thailand is an electronic visa that can be requested and delivered online. Applicants can complete their application online, upload the required documents and pay the visa fee online. Once the application is accepted, the applicant will receive an electronic e-Visa which they must print and present upon arrival in Thailand, in addition to their passport. The application process is generally faster and more convenient than that of a traditional visa, and can be completed from anywhere with an internet connection.
