That's interesting. Do you know more? I don't know whether you are correct or not, but it seems rather odd that an administrative agency, using its delegated power from Congress to add/remove/change regulations, cannot add/remove/change regulations without Congress' consent.
I mean, if Joe Blow at the FCC steps out of line, then he gets called up on the Hill for a verbal thrashing--that's where "oversight" comes in. (And Congress can legislate a change--in effect, withdrawing its "consent").
All the Executive Branch has to do is issue Executive Orders pertaining to the topic at hand.
Here is an example of what can happen with EO, (note I mentioned can):

Or this:
Executive Order: United States-Mexico Border Health Commission
By the authority vested in me as President by the Constitution and the laws of the United States of America, including section 1 of the International Organizations Immunities Act (22 U.S.C. 288) (the “Act”), and having found that the United States participates in the United States-Mexico Border Health Commission (USMBHC) pursuant to the United-States Mexico Border Health Commission Act, Public Law 103-400 (22 U.S.C. 290n et seq.), I hereby designate the USMBHC as a public international organization for purposes of the International Organizations Immunities Act. I hereby extend to members and employees of the Mexican Section of the USMBHC the same privileges, exemptions, and immunities as are accorded under similar circumstances to officers and employees, respectively, of foreign governments with regard to the laws regulating entry into and departure from the United States as provided for in section 7(a) of the Act (22 U.S.C. 288d(a)). No other privileges, exemptions, or immunities of the Act are extended under this order
Or try looking into “Totalization” sometime 1rudeboy.
