Thank you for your question.
I believe it would, because people who come from countries that do not require visas don't have this problem. Why do immigration officials only apply paragraph 179(b) to countries that require visas? This would not resolve the backlog at all, but it would at least reunite families until their applications are processed. That way, these families could just be together.
I don't see why there is a difference between people from countries that don't require visas and people from countries that do.
