Okay, the user wants me to translate "non-mexican" into Thai. Let me check the rules again. The first rule says to translate all content into Thai. The second rule states if it's already in Thai, leave it as is. The third rule is to provide only the translation without explanations.
So, "non-mexican" is in English. I need to translate it. The direct translation would be "ที่ไม่ใช่ชาวเม็กซิโก" which means "not Mexican." I should make sure there's no existing Thai script in the input, which there isn't. Just output the translation without any extra text. Let me confirm the translation is accurate. Yes, that's correct. No explanations, just the Thai translation.
