How soon can Canadian skilled immigrants get a second letter after they get FN?

Where did you hand it in? By what category? Is it a provincial nomination or CEC nomination or a direct federal nomination of skilled immigrants? Generally speaking, FN and ME (physical examination) are obtained at about the same time. You can send an email to Buffalo to ask. I was nominated by the province and finished it in 8 months. If you are in the federal category, the buffalo office may take up to 22 months, but this is rare.
