Yes. Regulation § 825.307(f) addresses this situation: “Medical certification abroad. In circumstances in which the employee or a family member is visiting in another country, or a family member resides in
another country, and a serious health condition develops, the employer shall accept a medical certification as well as second and third opinions from a health care provider who practices in that country. Where a certification by a foreign health care provider is in a language other than English, the employee must provide the employer with a written translation of the certification upon request.”
The definition of “health care provider” includes a practitioner from another country: “A health care provider listed above who practices in a country other than the United States, who is authorized to practice in accordance with the law of that country, and who is performing within the scope of his or her practice as defined under such law.”
