For FAA currency purposes, must flight time be in an N-registered aircraft? I currently hold a Commercial Pilot Certificate issued February,2018. My Flight Review has to be done no later than February 2020.

I have convalidated my FAA License to Colombia. The 90 day currency for carrying passengers applies to both FAA and Colombia.

If I fly Colombian airplanes, does that flight time apply to the 90 day requirement in the U.S.?

In other words, can FAA certificate currency be demonstrated in non-N-registered airplanes?
14 CFR 61.57(a)(ii) details "category, class, and type" but does not mention registration of the aircraft.
