Went to MTT today for Short Term Visa Ext, Amnesty.
Was told NO since my current 30day stamp expires Oct 21. They do not want to see me back until the 21st and not the 20th.
So much for going early to help them reduce the rush.
TLDR : Answer Summary
The user visited the immigration office to apply for a short-term visa extension before their 30-day stamp expiration but was informed they must return on the exact expiration date, October 21. Commenters noted that only those with specific prior stamps and extensions can apply earlier, indicating strict regulations on early applications.
