Got my 10 year LPR; 15 y/o son got it but 2 younger sons never did

[MrsChinita 1]

Guys, I have a serious issue here. My 15 year old son and I got our 10 year green card in July. We received our bio metrics letter in May. My 2 younger sons (13 and 12 years old) never received any bio metrics letter. I was told at the office (where we had our bio metrics done) that they don't need to have their pictures and fingerprints done because they are minors. So all along I thought that they will send me their new 10 year green card. But now that we are ready to file my N-400 and their N-600, I realized that USCIS didn't send me the 2 younger sons' green cards. Whatam I going to do now? I know I added them in my petition papers so I know I didn't make any mistakes on my part.

--I got bio metrics done and same thing with my eldest son.

--I got my 10-year green card and same thing with my eldest son.

--I filed for my other 2 sons, never got any bio metrics letter from USCIS.

--No green card for my 2 younger sons

Now, their old green cards already expired...what am I going to do now? I am at a loss here.
