OK to send electronic signature on/after Feb. 1?

<p>We did not realize S needed to also electronically sign - we had obtained the parent PIN ages ago. Filled out FAFSA yesterday (Saturday, 1/29) and did submit it online. H did sign electronically. Applied for S a PIN. I got the impression that just so it was submitted by Feb. 1st, things were fine. Now, reading other posts, I am wondering about this. Can anyone help??</p>
