Yes, it is possible to obtain a 6-month visa for Thailand, specifically a Multiple Entry Tourist Visa (METV) if you apply from your home country or a country where you have legal residency. However, there are certain requirements, such as demonstrating sufficient funds and potentially possessing a valid employment letter. If the individual is already in Thailand, they cannot apply for a new 6-month visa; they will need to consider different options.
