No, both extensions are NOT in the same calendar year. No, both extensions are NOT counting consecutively and does NOT start counting per your February extension. Each entry is UNIQUE and treated individually. There is no such thing as a February extension if you leave in April. Your new entry in 2025 will exclude February, so your entry calendar year will be from April 2025 to December 2025. 1 extension PER entry. Because the calendar year exclude previous entry and start counting the day you enter until December 31.
The counting start the Day you enter the country. You don't seem to have any knowledge about how the DTV work, or how extensions are calculated. Day 1 is your entry, which may or may not go to 365 days (extension at 180 days). It depend on you if you want to stay the full amount or do a quick border run and re-enter. What you can't do is extend in February and let's say August, without leaving the country.
You are failing to understand that your November 2025 would be your FIRST eXtension of the year, not your 2nd. The second that you leave (April 2025), the year END in relation to your entry and past extension. it reset April 2025 upon coming back. Or, to make it simpler, ONE extension PER entry.
There is no such thing as 2 extensions in 1 year. You are confusing border run with extension. You said, and I quote "leave april 2025". the second that you leave, you come back on a NEW entry, therefore you are at 0 extension for that year (for that entry).
The hate often come from angry old foreigners that hate their life.. I know how open to social media presence Taiwan is so it's no wonder they treated your application seriously. I'm 38 so people older than me didn't grow up with the internet and barely know what Tik Tok is. I have 200k YT subs so I know that space, and not surprise that you got it in Taiwan. There are other countries where you would not have gotten it because it's deem too obscure of a job for them to understand. But Taiwan and social media go hand in hand.
