Kids Visiting in Taiwan

Hello. I am an Expat living here in TienMu. I have a residence Visa (Working) and all my paperwork is in order. I am divorced, and my kids (boy 10yo / girl 6yo) will be visiting this month. The plan is for them to stay 3 weeks. I am an American, but they will be travelling on Italian passports. Is there any issue visa-wise, for them to stay here for 3 weeks on a Landing/Tourist Visa? Thanks for any help/guidance.
