Hello! I have a sister in dubai and like 5years ago she took caregiver course and now she is in Dubai she wants to apply here. She works as a secretary in there, but she had a certificate of 6months live in caregiver. She wants to apply here as a caregiver, I inquire on the agency but the agency told me that the course is not effective anymore since it was 5years ago and must be at least 3years ago... Is this really true? Its only good for 3years? thanks!
