My Taiwanese wife got removed from the Household registration due to more than 2 years abroad

So like a visa run. I had no idea HR was similar to a foreigners visa in regards to being avle to lose it this way. Really good to know, my wife had no idea either (taiwanese).

Out of curiosity and future reference, does a transit run count? Like say I buy a ticket from SFO to PEK or NRT that transits through TPE, and the layover is like 8 hours or something. Is it enough to exit the airport and then re-enter the airport to keep it active? Would I also have to deal with the fact that my flight is a transit and would need to tell the airline that Iā€™m going to exit customs with my TW passport?
