Remaining on the Waitlist?

So question: are we supposed to mail the postcard AND confirm on the portal thing that we want to remain on the waitlist? I said I did on the portal, but never received a confirmation or anything. Is this normal?

Do both! DD got in off the waitlist last year, but I’m sorry, can’t remember if there was an online confirmation or not. Can’t hurt to also mail the card! And good luck!

Mail return. Alternatively, you may submit an online response …
So you do only one method.
Otherwise admission will try to make you to remain on the list TWICE.
and I don’t think it’s helpful.

Sending in both is not going to put you on the list twice. Princeton admissions are more organized than that.

I said TRY " admission will try to make you to remain on the list TWICE."
When admission see the second request, admission will find he/she is already in the wait list.
