Can I have a return ticket beyond the 60 days for a Tourist Visa and what does an invitation letter need to include?

The user inquires about obtaining a 60-day Tourist Visa while planning to stay in Thailand for approximately 3 months, using a 30-day extension. They want to know if it's necessary to show a return ticket within the initial 60 days or if a return ticket for the extended period suffices, as well as the details required in an invitation letter from a Thai friend for accommodation proof. Comments from others indicate that while a return ticket should generally align with the 60 days, having arrangements for the extended stay is helpful. Additionally, proof of accommodation can often be a reservation for a hotel during the stay, rather than a personal invitation letter.
