Hello LaJasmine. I am not a member of Sigma Gamma Rho. However this is the information found on their international website:
A person may be admitted for membership in an undergraduate chapter only while in attendance at a four year accredited college or university, or in a liberal arts transfer program of a junior or community college, once they submit proof of intention to enter and obtain a degree from a four year school.
You may want to go directly to the website at
www.sgr1922.org.
Good luck!
