The regulation covering the flight review, 14 CFR 61.56, lists acceptable alternatives. Compliance with that section by persons holding a restricted private pilot certificate is mandatory: see interpretation to Collins.
If a US flight instructor is unavailable to complete the review then consider using the WINGS Pilot Proficiency Program. It will require an FAA Safety Team Program Manager (FPM) at a suitable FSDO to manually approve some qualifying flying activity such as a skill test or proficiency check done in connection with the foreign licence.
