Went from visa exemption stamp into Non-O 90 days thai child dependent visa in Thailand. Submitted the whole paperwork in 2 sets that is needed for the 1 year extension (hoping I could get one year straight away). Am I right to assume that for the 1 year extension I will have to resubmit everything even if it's the same immigration office? Couldn't ask the IO as he wasn't bothered. He also stamped me a 3 days earlier date. I didn't see it straight away, just thought it was a weird date for the visa expiry. But didn't want to test my luck by complaining. Also, if a new rental contract is needed does it have to start 3 months prior to extension date or on the date of extension for a year (like 30 days before expiration of Non O 90 days)? TIA
