Can I extend my ED visa in Thailand with only one week left before expiration?

The poster currently holds an ED visa and has been out of Thailand for several months, leaving them with only one week remaining on their visa upon return. Several commenters advise caution, suggesting that immigration may inquire about the extended absence, and underline the importance of having proof of enrollment and a letter from the educational institution. Some recommend canceling the ED visa and applying for a tourist visa instead, while others believe that as long as the poster can demonstrate they are a valid student, they should be able to extend their visa without issues. Ultimately, there are concerns about potential denial of entry, indicating it's essential to have proper documentation and to be prepared for questions from immigration officials.
