Health Insurance
Health insurance is not currently mandatory for entry to Thailand but is strongly recommended.

Ensure your policy covers medical evacuation. Some long-term visa types may require health insurance as part of the application process.

Special Situations
Additional requirements for specific circumstances.
Children must have their own passport (family passports no longer accepted). Minors (under 18) traveling without both parents should carry a notarized letter of consent from the absent parent(s) authorizing travel, though this is rarely checked. Single parents should carry the child's birth certificate. For divorced or separated parents, custody documents may be helpful. Adoption papers should be carried for adopted children. Children follow the same visa requirements as adults based on nationality.
Pets entering Thailand require: (1) ISO-compliant microchip, (2) Valid rabies vaccination (at least 21 days before travel but not expired), (3) Health certificate issued by licensed veterinarian within 10 days of travel, (4) Import permit from Thai Department of Livestock Development (apply 30-60 days before travel), (5) CITES permit if bringing endangered species. Dogs and cats from rabies-free countries may have reduced quarantine. Certain breeds are restricted or banned. Pets must enter through designated airports (Udon Thani airport accepts pets). Expect inspection and possible quarantine period. Advance planning essential - process can take 2-3 months.
Tourist visa exemptions (60 days) can be extended once for 30 additional days at any Thai Immigration Office for 1,900 THB. Apply before your current stamp expires. Required documents: passport, TM.7 application form, TM.30 receipt (proof of residence reporting), passport photo, copies of passport pages, and proof of address. For stays beyond 90 days, consider applying for appropriate long-term visa before arrival: Non-Immigrant visas (for business, education, family), Retirement visa (for those 50+), or Elite visa. Multiple tourist visa entries may raise questions from immigration. Overstaying results in fines (500 THB per day, maximum 20,000 THB) and possible ban from Thailand.
While technically possible to exit and re-enter Thailand to obtain a new visa-exempt entry, Thai immigration has cracked down on this practice. Arriving by air typically allows 2-3 visa-exempt entries per calendar year before questions arise. Land border entries are limited to 2 visa-exempt entries per calendar year. Immigration officers have discretion to deny entry if they suspect you're living in Thailand on tourist entries. If planning extended stay, obtain appropriate visa type rather than relying on border runs. Keep documentation of genuine tourism activities.
Thailand does not have a specific digital nomad visa category currently (though one has been proposed). Working remotely for foreign companies while in Thailand on tourist visa is technically illegal but rarely enforced if no Thai income involved. For legal long-term stay while working remotely: consider Non-Immigrant B visa with work permit (requires Thai employer/business setup), Education visa (enroll in Thai language school), Elite visa (paid long-term residency program), or Retirement visa if over 50. Do not mention 'work' to immigration officers when on tourist visa.
Previous overstays are recorded in Thailand's immigration database. Overstays under 90 days result in entry ban: 1 year for overstay caught on departure, 5 years if caught by authorities. Overstays over 90 days result in longer bans. Previous visa denials, deportations, or blacklisting may prevent entry. If you have previous issues, consult with Royal Thai Embassy before booking travel. Being honest if questioned is crucial - immigration has full access to your history. Minor previous issues from years ago may not prevent entry, but recent or serious violations will.
The nearest land border to Udon Thani is Nong Khai (Thai Lao Friendship Bridge), approximately 50km away. Visa-exempt travelers can enter here, but note the annual limit of 2 land border visa-exempt entries. Visa-on-arrival may not be available at all land crossings - verify beforehand. Border hours typically 6:00 AM - 10:00 PM but verify current hours. Have exact change for any fees. Thai immigration and Lao immigration are separate processes. Ensure you properly exit Laos before entering Thailand. Some travelers use this route after visiting Vientiane. Transportation to Udon Thani available via bus, taxi, or private car.
