Some people were saying their reasoning for naturalizing was based on weaker passports when it comes to traveling. For us, it doesn't make a difference. My husband and I have both been allowed to enter any country we have traveled to (dozens--we are huge travelers). Any country he would need a visa for on his foreign passport, I would also need one as a USC. So we haven't. fortunately, had to worry about that. If he was from a country where traveling was prohibitive due to the passport, then it would factor into wanting to naturalize.
