You may need an embassy visa for Taiwan if you have a Laotian passport

Travellers may be eligible to apply for travel authorization to visit Taiwan for Business or Tourism for a maximum stay of 14 days. Travellers can apply for a Travel Authorization Certificate only if they hold a valid visa or residence permit or a visa or residence permit issued in the past 10 years by Australia, Canada, Japan, South Korea, New Zealand, a European Union country, a Schengen country, United Kingdom, or United States. Travellers can submit the eTA application online. Once the application is approved, travellers receive their eTA confirmation electronically. Approved eTA is valid for 90 days. Multiple entries within these 90 days are allowed. A valid eTA is required to board the flight. If the eTA is expired or doesn’t match the traveller’s passport information, travellers will not be able to board their flight. Please see the source for more details on the Travel Authorization Certificate.
