Just a heads up for people going to Samut Prakan Immigration office to file 90day report with just a _screenshot_ of a new TM30 registration(as that’s all you can get -Thailand 4.0 yay!): better bring a copy of your rental contract. They want it. I got the stamp as I still rent my old condo that I’m too scared of COVID (no masks on staff or residents)to go empty and could show that tm30 receipt, but was told I had to bring contact for new house next time.
TLDR : Answer Summary
When filing a 90-day report at the Samut Prakan Immigration office, it's important to bring a copy of your rental contract in addition to a screenshot of your TM30 registration. Although you might be able to use just the TM30 receipt, the immigration staff may request proof of your current residence, especially if it's a new address. Previous experiences indicate that having the lease on hand helps alleviate any potential issues.
