what are the legacy "benefits"?

I know I'm my house all legacys are asked back until the final round unless there is a good reason for them to be released before.

^^exactly what she said. Legacies have to be asked back each day except preference unless there is a strong reason to release them before.

That's not true for every house ^ we only have to keep them past the first round but can release them after that

In my house we release legacies after the first day if they are a BIG grade or pr risk or if they are just completely unable to hold a conversation. Otherwise they stay. For ALL houses, if a legacy goes to her legacy house's pref night, she is automatically on the bid day list. So no, legacies don't automatically get invited back every day until pref, I'm sure you've heard this but being a legacy is not a "golden ticket" on to the bid day lawn. Hope this was helpful!

Legacy policy varies from sorority to sorority. Some have to invite you to the first invitational round after open house, others don't. Some place a high priority on pledging legacies, others don't. typically, if a chapter does not like a legacy they will release her early, no matter what the policy is, so she can find another home. If a chapter keeps you until pref, they see you as a potential sister. Most sororities would not invite someone to pref they don't want as a sister. If you are still there, you are probably very much wanted.

Don't forget the money if Mom, Grandma, etc. supports the house financially your in. Money talks.
