Although a visitor visa allows U.S. citizens to stay in the country for up to 60 days, the Taipei Economic and Cultural Office (TECO) requires applicants to have a passport with a minimum validity of six months.
As is the case with most, if not all, visa applications, you must submit two passport-sized photos with your application. The photos must be two by two inches.
TECO does not charge a visa fee for U.S. citizens applying for a visitor visa to enter Taiwan. Other nations that are also exempt from a visa fee include Ecuador, Fiji, Gambia, Grenada and Nevis, Guatemala, Honduras, Kiribati, Korea, Malawi, Marshall Islands, Nauru, Republic of Nicaragua, Palau, Peru, Saint Christopher, Saint Lucia, Saint Vincent, Burkina Faso, Colombia, Commonwealth of Dominica, Sao Tome and Principe, Singapore, Solomon Islands, South Africa, Swaziland and Tuvalu.
Nonetheless, as of June 2010, TECO requires U.S. citizens to pay a processing fee of US $140.
Unless you are a minor, you must provide evidence of sufficient financial resources to cover your trip before your visa can be issued. TECO accepts bank statements as proof of financial support. The rationale behind this requirement is to ensure that you do not become a public charge to the Taiwanese government.
You must also complete and sign a visa application form. You can obtain the form by visiting the homepage of TECO in Seattle. If you are seeking a multiple-entry visitor visa, you must provide a company letter detailing the purpose of your trip or submit documented proof that you have relatives in Taiwan. Other requirements include a confirmed return air ticket and proof of no prior criminal record.
