I think Q1 is basically useless because like a Z visa you'll need to apply for a residence permit once you land in China. So instead of getting a Q1 you could just get a Q2 and then apply for the residence permit once you are in China. In fact when my work residence permit ran out while overseas this is exactly what my visa agent told me to do, i.e., get a Q2 and then convert to a normal work residence permit once I'm back in China.
