F1 Visa - Prof. Lic. requires 2 years interniship and OPT is 1 year

I am currently in a F1 Visa pursuing a Master in Counseling. Once graduated I need to do 2 years of Internship (3000 hours supervised), but OPT is only for 1 year.

How do I go with my Visa status once I finish the 1 year OPT and I still have one more year of internship?

Please help. Thank you very much I appreciate it!
