Is the visa application process different for a Malawian passport holder?

I am moving to Qingdao, China, in August with my two children. I will be teaching at Qingdao Amerasia International School. QAIS is applying for a Foreign Expert Certificate Visa on my behalf. They have asked for a copy of my passport and my children's passports. My son and I both have Canadian passports. My daughter however, has dual citizenship of both Canada and Malawi. She is three years old and was born in Malawi. She has a Malawian passport and a Malawian birth certificate. Will that make a difference when applying for our visa? She does have her Canadian Citizenship Certificate, but she won't have a Canadian Passport until next year.

As part of the list of documents QAIS need, they have also asked for a digital passport sized photo of myself, and my two children. I have a passport photo of myself and my daughter already. Can I just scan the photos to email them, or do I need to have the photos retaken.
