not rush again!??

[sweetchicky]

Hopefully someone who had been through something similar or knows might have an answer.
Ok, I went through rush this past fall and was a proud new AOII. I went through pledging and about half of the new member period. There were some family illnesses that caused me to have to drop the semester as well as leave school.
Starting this semester I transferred back to my original school and would like to join the same sorority different chapter obviously. I contacted the president of this chapter and the chapter has invited me to dinner tomorrow and I am going.
My question is, do I have to go through getting another bid and even pledging again?

Thanks Greek Chatters!
