What are the disadvantages of Antigua passport immigration?

The disadvantage of Antigua passport is that it is the only passport item with immigration supervision. The first passport renewal five years later requires five days' residence in Antigua, and then there is no need to renew it.

The advantage is that it is the only visa-free passport project in Canada, which can replace the maple leaf card to enter and leave Canada freely, and it is visa-free for 13 1 country.
