Should I get a tourist visa for Thailand before traveling or after I arrive?

Travelers going to Thailand for 32 days are advised to consider obtaining a tourist visa before arrival, as it cannot be obtained while in the country. Some users suggest applying for a visa at the home embassy to avoid complications and save time at the immigration office in Thailand. Alternatively, one could enter Thailand without a visa if eligible for visa exemption and then extend their stay at a local immigration office for a fee.
