What kind of visa should I apply for my kid?

I am Ukrainian citizens and I have 2 years Temporary Residence Card that will be expired in 2020. I am going to deliver my baby in November 2018 in Taiwan and the child will take Taiwanese passport. I intend to come back to Vietnam after having my baby. In this case, what kind of visa should I apply for my kids?
