What do I need for my second visa extension at Blue Tree Immigration Thalang after previously extending my stay in Thailand?

In this discussion, the original poster (OP) seeks advice on the requirements for a second visa extension at the Blue Tree Immigration Thalang after already having obtained one 30-day extension this year. Commenters clarify that a second 30-day extension is generally not permitted if it has already been used on the current entry stamp, and recommend checking the visa type and entry details. It is noted that the OP needs to ensure they have the required documentation, such as the TM30 form, and possibly have to apply for a new visa entry if they wish to extend their stay further.
