On my final steps for assembling hubby's green card renewal

I just realized that the instructions did not specify if photocopied items should be in color or black and white? and also didn't say if I had to magnify the photos or not.

In particular

We need to make copies of the green card and our son's birth certificate.

Is there any format that's causing issues with RFEs? I was going to make standard color copies at my home...

Please has anyone been assigned interview date or does anyone know if Interview is currently ongoing at Lagos Embassy?

CR1 visa.
