<p>I'm on my 4th semester in community college. When I first started college I did not have a social# so I did NOT put one on file instead I applied for exemption from our of state tuition. Now I am about to transfer, when I reviews my transcripts I noticed there was a social security. I never notice until now. How complicated is it to change number on file. Should I call admission or is it better to go in person.</p>
