My cfi expires in June. I've signed off 4 students for checkrides and all have passed. I've got another student who should be ready to go in about a month if all goes well. How long does it take to complete the online renewal (gliem, american flyers, etc) if I can't send this student for his ride on time? I'm worried the timing may not work out and I'll be stuck having to renew online with a minimal amout of time.
