If the president was an American citizen for more that 14 years, then maybe.
Theodore Roosevelt was the first to visit a foreign country while he was in office. He was also the first to take off in an airplane, although is was a very short flight. He may have been the first to ride in a car, as well.
Joe Biden
No, there has never been a girl president, but in the future we might have one!
The president is the one who hosts a cabinet meeting to discuss foreign policy. This is one of the powers that have been expressed to the president by the constitution.
Switzerland
There is no evidence that he has. As an American, he uses the U.S. coin system. On the other hand, if he was a coin collector as a child (and he certainly might have been), he may have had some coins from foreign countries. But there are no reports that he has purchased any foreign coins recently.
That depends on the constitution of the country. As you have not been specific about the country, it is not possible to be more helpful.
There have been several. It depends which country you are referring to.
Herbert Hoover. He was the president of The People's Republic of Quebec before it was annexed by Canada
No. In fact, as of 2018, only 1 US president has ever been bilingual.
This depends on the country. Different countries have different limitations on who can be president and for how long.
President Obama's supporters would say this is an unfair question, because he has not hurt America at all. They would say he has helped the country, not hurt it. It is mainly his political opponents who would say he has hurt the country. From the point of view of the Republicans who want to defeat President Obama, they believe his policies on the economy and on health care and on immigration have hurt the country. But his supporters would say his policies have been largely beneficial to the country and he should be re-elected. On the other hand, there are some countries that oppose American foreign policy and they do not agree with the foreign policy views of this president, just as there was similar disagreement about the previous president (George W. Bush). Iran, China, Afghanistan and Pakistan have had policy disagreements with the U.S. government, for example. But again, the question was about Obama hurting the country, and even here, the answer would be partisan, with supporters saying his policies (especially about fighting terrorism) have been very well received in many foreign countries, and his opponents saying he has not done an effective job at all.
