Assuming you're Nigerian and the Nigerian authorities don't impose a yellow fever vaccination requirement on their citizens to leave the country (many African countries do) then you first have to find a country that doesn't require the shot to enter or transit (such as European countries) before flying to Thailand.

However, that isn't a guarantee because Thai immigration still pulls aside all Nigerian nationals to check their yellow fever vaccination certificate.

In theory, a minimum 10 day stay in a non-yellow fever country should negate this requirement, but it's uncharted waters.

If you're concerned, you might want to consider getting a "contraindication to vaccination certificate ".

I don't know if the Thai authorities will accept this for quarantine free entry.

Singapore imposes a 6-day quarantine on holders of this certificate (meaning anyone who is medically unfit to be vaccinated against yellow fever) and I suspect the Thais are the same but I don't know for sure.

@Cesar ******

Yep they probably won't even issue you a boarding pass since the Thailand Health Pass form is a mandatory requirement for boarding a flight from those countries. Airlines that don't comply could be fined.

@John *********

It's a certainty to be denied entry and in fact, you need to fill out the T.8 health form with your yellow fever vaccination certificate uploaded just to get issued a boarding pass. This requirement was imposed last August in the wake of the monkeypox 2.0 "outbreak".

Yes. You need to fill out the T.8 Thailand Health Pass otherwise you won't be issued a boarding pass.

@John ******

Yes for Myanmar it's also 14 days.

@John ******

Sorry, for Brunei it might indeed be 14. It's 15 for Swiss, Luxembourg and Russian citizens as well as Japanese.

@John ******

It's 15 days for citizens of Brunei, Switzerland etc. Not 14.

Get an extension at the immigration office if possible. If you did go out of country, it can't be to Thailand. Has to be to another country.

@Henrik ****

Most Thai consulates don't call you in for interviews. However, it's still best not to enter Thailand until your visa has been approved.

Anonymous participant 959 Yes, correct. One individual down in Krabi claims otherwise, but I told her she's wrong and a "know it all". Usually, you'll receive a rejection email after the initial filing, something she probably isn't aware of.

I don't know why they created this bureaucratic nonsense, although at least you can always mail your 90 day report in rather than going in person, regardless of whether it's your first or 10th time following your last re-entry.
