How long before my 180-day visa ends should I seek an extension at immigration?

To apply for an extension to your stay in Thailand before your 180 days are up, it is generally recommended to start the process at least 15 to 45 days in advance, depending on the immigration office you're visiting. However, securing an extension can be challenging, as many expats find that immigration officials may create obstacles. A popular alternative is to undergo a 'border bounce,' which involves leaving the country temporarily and re-entering, though this can be more costly.
