Before Covid, the hiring process for most of us to be hired from overseas has been this:
Sign the Contract in our home country.
Get our Work Permits issued and emailed to us while in our home country.
Depart once Work Permit arrives. A process of about a month.
And, as of 10/13, upon arrival you'll be asked to follow 7 days of
self-monitoring. Quarantining is not required.
So, from March 7th, the policy of the relevant health and policy ministries in Taiwan is to reopen the hiring of teachers from overseas. Definitely good news.
And, with the disease coming more and more under control, the
rule on wearing masks outdoors has been lifted - as of 12/1/2022.

What about my ARC?
Following the process above you'll be arriving with a Work Permit. Once you're past quarantine and working, your ARC is usually issued about two to three weeks later. And, since you ALREADY have a Work Permit you'll be OK to start teaching.
