I have a Work extension, and my non-Thai wife and son piggyback on this. It expires on 30 November 2024. I am just preparing the paperwork for our annual Immigration visit, and noticed that my 9-year-old son's UK passport expires on 27 October 2025. I don't have time to renew his passport before we go to Immigration.
My understanding is that he will only be given an Extension until 27 October 2025 (his passport expiry date). I will get his new passport in January and get the Extension date transferred.
My question is what will happen next year when we need to extend again in November? Will Immigration overlook a 34-day overstay for my son (28/10/2025-30/11/2025) as children can't be fined, and give him an Extension that matches ours?
Or, when we go to Immigration next month, should we all apply for Extensions up to 27 October 2025 instead of 30 November, to keep everything in sync?
TLDR : Answer Summary
The user is seeking advice about extending their son's visa, which is linked to his UK passport that expires on October 27, 2025. Since the son's visa extension will only be valid until the passport expiration date, the user is concerned about the implications of needing to extend again in November 2025 and whether Immigration will penalize the child for the potential overstaying. The advice received suggests applying for visa extensions for the whole family up to the son's passport expiration date to keep everything aligned.
