This is a tricky one and I’ll speak to what I know but I’m not a legal expert.
The vast majority of internships require the person to have a right to work in the U.S, so international students who have a visa status sponsored by their college or university, or are authorized to work in the U.S could intern but it depends on the place
Most executive agencies do not since US citizenship is required
For Congressional offices, from what I know, theoretically yes a foreign national could intern but I don’t think if they can be paid (many offices don’t pay anyways) and some offices/committees (e.g. House Foreign Relations Committee) don’t allow it.

Many Think Tanks (e.g. Brookings) allow this.
