Over the last few years, there have been many changes in Amateur Radio licensing law and practice in Taiwan. One of the major changes is the abolition of the Morse Code proficiency requirement in order to obtain a Second-Class (rough FCC General equivalence) operator license. Another is using FCC pool questions in all relevant sections down to the wording and answer choices literally translated. Not sure whether the questions will be updated when then FCC pool for the license classes are updated.
One may bring in amateur radio equipment provided that accompanying paperwork is completed and is not allowed to be operated until it is inspected and approved at the NCC (National Communications Commission) office. It may not matter anyway to a foreign guest operator, because they cannot use their own equipment.
What has not changed is that Taiwan (including Kinmen, Matsu and Penghu outlying islands) does not share operating authority with any other jurisdiction, period.
Operators licensed in their home jurisdiction may apply for temporary operating authority at a local sponsor station: http://www.ctarl.org.tw/bv5ya/2009-10/VSTR-op.htm
While the link is dated 2009-10, my understanding is that the link is current as of this posting. A list of guest operator permit grants may be found here: http://www.ctarl.org.tw/bv5ya/outnews.htm
What has also not changed is that one must possess a valid Alien Residence Certificate (ARC) or Passport issued by the Republic of China (Taiwan) to apply for an Amateur Radio Operator License and sit for the exam.
The CTARL face book page is limited to news feed of their activities. Current general information remains on their web site. Actually all the information is there, it just may not be presented in the manner you expect.
