How do you apply to become a legal midget i am exactly 4' 9'' and havnt grown in 4 years?

You are not technicaly a "midget" or dwarf unless you have teh gene(s) that causes dwarfism. You might want to go to a specialist to determine if you hav those genes because sometimes dwarfism can affect your health in ways other than just beling below average heighth.

Hope this helped.
