Immigration Forum / USA Marriage Base / July 2006

My husband had his AOS interview today in San Bernardino, we were told
that his file is approvable but there was administrative stuff to be
done still. We were given a notice that tells why our application is
still pending, to inquire on the case via infopass if we do not recieve
a response, and he marked "Please inquire after 90 days: Additional
administrative checks have been submitted but have not yet been
resolved."

Is this most likely the background checks still pending? I assume that
it is, but the wording throws me off, and I haven't noticed in the
posts here about pending checks, people being told to come back in 90
days.
