Thanks for the link. The Section in question is an excerpt from the Adam Walsh Child Protection and Safety Act of 2006 and is highlighted below.
This applies when the individual seeking an immigration benefit is a convicted sex offender. and is applied in conjunction with INA: ACT 204 - PROCEDURE FOR GRANTING IMMIGRANT VISAS
"SEC. 402. BARRING CONVICTED SEX OFFENDERS FROM HAVING FAMILY-BASED PETITIONS APPROVED.
(a) Immigrant Family Members- Section 204(a)(1) of the Immigration and Nationality Act (8 U.S.C. 1154(a)(1)), is amended--

(2) in subparagraph (A), by inserting after clause (vii) the following:
`(viii)(I) Clause (i) shall not apply to a citizen of the United States who has been convicted of a specified offense against a minor, unless the Secretary of Homeland Security, in the Secretary's sole and unreviewable discretion, determines that the citizen poses no risk to the alien with respect to whom a petition described in clause (i) is filed.
`(II) For purposes of subclause (I), the term `specified offense against a minor' is defined as in section 111 of the Adam Walsh Child Protection and Safety Act of 2006.'; and

(b) Nonimmigrants- Section 101(a)(15)(K) (8 U.S.C. 1101(a)(15)(K)), is amended by inserting `(other than a citizen described in section 204(a)(1)(A)(viii)(I))' after `citizen of the United States' each place that phrase appears."
In the circumstances the OP has described, that of husband/wife with the husband being the USC with a felony and assuming this is not a sexually related felony directed at a minor and that the Alien Spouse is over 18, then I would say that there is nothing here that says that the USC husband cannot petition for his Alien Spouse.
Here is the question to the OP.
Is the felony your husband was convicted of a sexually based felony?
If yes, was the victim a minor?
If yes, are you a minor, as in are you under 18?
If yes, he may have a problem petitioning for you.
If you are over 18 and the Secretary of Homeland Security believes that he poses no threat to you, the spouse, then you may be ok.
As always, consult an a competent Immigration Attorney if you have legal questions that you need answered. This is not intended as Legal advice.
