Does a family reunion visa for the United Kingdom require MFA legalisation of Thai documents?

Short answer: the most common reasons visa supporting documents get returned are: name spelling that differs from the passport page, Thai/Gregorian date mismatches, unclear official seals or signatures, and certificates issued too long before submission. We check all four before filing and supply an indexed document schedule so the officer can verify each item quickly. Call 094-895-8999 if the file is urgent — express handling in 1–2 business days is available.
