Bringing family to the US

[texas_bunny 0]

I was just reading this on the USCIS website ( http://www.uscis.gov/files/article/A1.pdf ) and saw this paragraph and began wondering:

What if I filed a petition for a relative when I was a

permanent resident, but I am now a U.S. citizen?

If you become a U.S. citizen while your relative is waiting for a visa,

you can upgrade your relative's visa classification by upgrading your

petition. Husbands/wives and unmarried children under age 21 of

U.S. citizens have visas immediately available to them.

• If you become a U.S. citizen after your petition is already

approved and sent to the State Department, you should notify

the NVC that you have become a U.S. citizen by sending a copy

of your naturalization certificate to the NVC. Please include a

letter with information regarding your relative and a copy of the

petition approval.

• If you become a U.S. citizen and your relative's petition has

not yet been approved by USCIS, check our website or call

customer service for information.

Under what circumstances could you Petition for a relative while being a LPR? I thught you couldn't petition for relatives while being a LPR? Just wondering if I am not understanding something.
