no they have no powers outside the usa unless the host country like UK crporate with them
The act of 'harboring' usually refers to hiding someone from the police - with the intent of preventing their arrest.
They are not really comparable. The CIA does not enforce any laws, but collects intelligence overseas. There are no circumstances where the CIA can legally arrest you (besides the inspector general arresting CIA employees for, say, stealing money from the CIA). The FBI can arrest people in the US for violating federal laws, and collects intelligence inside the US.
a cia file is a federal file on someone
The CIA is not law enforcement, and therefore, cannot arrest U.S Citizens. The CIA is strictly an intelligence agency that collects information from foreign nations. If the CIA needed to have an American citizen detained, they would delegate through the FBI.
The CIA are based in central London alongside the houses of Parliament, near London Bridge.
Yes they may! And in some cases they may have jurisdiction in other countries ( with permission. ) to make an arrest. Although usually the State's patrol of the arrestee will make the arrest. The CIA will supervise the case while the person is prosecuted on either a State or Federal level. Usually it's also on a Federal level which where the United States Marshall's Service will step in and do the arrest and detain them. CIA may also do the interrogation. If it includes terrorists in foreign countries one of the military police services in one of our five military branches our country will make the arrest, and the CIA will supervise. Understand the CIA is more of an investigative branch, they do in depth studies of cases for the military and supply the intelligence for them. Along with other branches of the United States Government if needed. - Have experience working with the CIA.

Circumstantial evidence is definitely enough to arrest someone - a person is arrested not just for questioning, but also to preserve other evidence, like forensics. Circumstantial evidence might not be enough for actual charges to be made, but the arrest might yield more concrete evidence.
how do i find out if someone has a active warrent for thier arrest
You can view the arrest record of someone at your local police department. The arrest records are public and anyone can see them.
That depends on the laws of your country. Here in the UK, they can keep you for up to 48 hours - then they have to charge you or release you.
No. People can call the FBI or CIA any time they want. If you have done nothing wrong, the FBI or CIA will do nothing.
