For foreigners in Thailand
Stay in Thailand, sorted.
See which visas may fit you, follow a checklist to the immigration counter, and always know how many days you have left.



How it works
Five steps, the same for everyone
From the first question to the day you hand in your papers.
Ask
A few questions about why you are here and how long you want to stay.
Scan
Your passport, read on the phone. The picture is never kept or sent.
Options
The visas that may fit you, ranked, with what each costs and needs.
Complete
A checklist to the counter: documents, forms, fees and the office to go to.
Track
Your days left, 90 day reports and every deadline, with reminders.
Options
See every way you might stay
Answer a few questions and Yoo Dai ranks the visas that may fit you. Each one shows the cost, the documents and the office, with the official source and the date it was last checked.
- Ranked for your answers
- Every rule shows its source
- Immigration officers decide, and the app says so




Track
Every date, in one place
My stay counts down to the date on your stamp. Add plans with reminders, and when you pick a visa Yoo Dai lays out every step to the counter, down to what to bring on office day.
- Days left and days in Thailand this year
- Plans and reminders for every deadline
- Office day checklist with member tips
