Is there a time limit to activate a Thai visa after it has been issued?

5 years

There’s no “activation period” for multiple entry visas. The minute the visa is issued it is active so you could hypothetically enter 4 years later and the visa is still valid but you’d only have a year left on your visa.

You have 5 years to come the visa starts the day it was issued…..

Anonymous participantYes, the visa type and “Enter Before” date are the key things to check. If your visa was only approved a couple of days ago, look at the e-Visa approval letter for the exact date you must enter Thailand by. If mid-November is before that date, you should be fine; if not, you may need to contact the Thai embassy/consulate that issued it.

You could also consider reading a book or two before your trip. I’d recommend Unlock Thailand by Isla Rey on Amazon—it includes all the info and insights you need. You should check it out. A very good companion

I think it is 3 months and mod November is fine but worth exploring.
