Medical exams are typically valid for 12 months for immigration purposes. However there is temporary policy that if you ever done medical exam before for any visas, they will still consider that exam even it's expired.
Birth Certificate
IRCC prefers a birth certificate to confirm date and place of birth, but if your wife doesn’t have one, here’s what you can provide:
Alternative documents:
School records (school leaving certificate / transfer certificate showing date of birth).
- Baptismal certificate (if applicable).
- Affidavit of birth (notarized, stating her date and place of birth, and explaining why a birth certificate is unavailable).
- Government-issued documents (passport, Aadhaar card, etc., showing date of birth).
Recommended: Provide as much alternative documentation as possible (preferably government-issued records). Also, include a Letter of Explanation detailing why the birth certificate is unavailable and what documents you’re providing instead.
