Can I claim priority to a provisional application filed in a foreign country?

No, you cannot claim priority to a provisional application filed in a foreign country. The MPEP 213.02 states:

‘Note that a foreign filed provisional application is not eligible for priority benefit.’

Priority claims can only be made to non-provisional applications or other types of applications that are recognized under the Paris Convention. Provisional applications are unique to the U.S. patent system and are not recognized as priority documents in foreign countries or under international agreements.
