What documents should I prepare for immigration when entering Thailand with an ED visa?

When entering Thailand with an ED visa, it's important to prepare certain documents for immigration. While your visa itself confirms your entry, having additional documents can help. It's advisable to carry a bank statement and any proof of your purpose for studying, such as an invitation letter and enrollment confirmation from your school. Be ready to answer questions about why you're learning Thai and details about your schooling. Additionally, be aware that airlines may ask for proof of a return flight, even if it's not a strict visa requirement.
