中華民國政府如果不信任人家，那就不要給人家國籍。
如果給了人家國籍，那就應該給人家政治權利。
目前的法律是讓每個歸化者都必須當十年二等國民。
我有限的認知，好像還沒有見過第二個國家有這樣的規定。

XComhghall U.S. Constitution
Article I, Section 2, Clause 2
No Person shall be a Representative who shall not have attained to the Age of twenty five Years, and been seven Years a Citizen of the United States, and who shall not, when elected, be an Inhabitant of that State in which he shall be chosen.
Article I, Section 3, Clause 3
No Person shall be a Senator who shall not have attained to the Age of thirty Years, and been nine Years a Citizen of the United States, and who shall not, when elected, be an Inhabitant of that State for which he shall be chosen.
中華民國這個規定大致是，不能當直轄市、省轄市、縣、縣轄鄉、鎮、市長、議長、議員，不能當村、里長，但能當區、鄰長。
