It appears that the surviving tica spouse can't receive benefits in CR if they're not a US citizen and haven't lived at least 5 years in the US, during which time the marriage was in effect (with a few specific exceptions that probably wouldn't apply to most of us). I'm less clear whether that means they can't at least receive those benefits IN THE US (if not to the survivor directly if they move to the US, then to some 3rd party who will privately forward the payments to them in CR), but imagine similar restrictions would exist there too.
Additional residency requirements for dependents and survivorsIf you receive benefits as a dependent or survivor of the worker, special requirements may affect your right to receive Social Security payments while you are outside the U.S. If you are not a U.S. citizen, you must have lived in the U.S. for at least five years. During that five years, the family relationship on which benefits are based must have existed.
Ch*ldren may meet this residency requirement on their own or may be considered to meet the residency requirement if it is met by the worker and other parent (if any). However, Ch*ldren adopted outside the U.S. will not be paid outside the U.S., even if the residency requirement is met.
The residency requirement will not apply to you if you meet any of the following conditions:
You were initially eligible for monthly benefits before January 1, 1985; or
You are entitled on the record of a worker who died while in the U.S. military service or as a result of a service-connected disease or injury; or
