Hi everyone, how to apply DTV visa from Singapore.Anyone got visa from SG ?

Hey guys just scanning this forum for some updated info, and found a few things related but was hoping for any further advice. I was just emailing back n forth with the Thai consulate in Singapore as my family is looking to obtain a SETV there. We are currently in Thailand on a SETV and we just did our 30-day extension to give us our full 90 days. However, the consulate is advising me that we won't be allowed back in or approved for another SETV visa as we are only allowed 90 days within a 6 month period. Tod Daniels and a few others have mentioned this is an old rule that is no longer enforced...but it still leaves us feeling a bit uneasy. Is this a risky move or just continue with the visa application and fingers crossed when we re-enter the Kingdom? Thanks in advance guys!
