Just did my first 90-day reporting at Chamchuri Square this morning. Filled up the form on the groundfloor and they gave a queue number. Went up to 18th floor. Passed the form and passport to the 90-day reporting counter just in front of entrance. No copy of any document needed. They didn’t even ask to see the documents. Wait for the receipt and acknowledgment. Total about 20 minutes. Super! I am non- imm with multi Re-entry permit.
