H4 extension is ‘My Notice Was Returned To USCIS Because The Post Office Could Not Deliver It’ and denied. Will this affect out next extension?

Since you and your spouse were both denied, the only thing that your daughter would be waiting for would be another denial. You can continue pursuing it, ie. Freedom of Information Act, if you so desire, but the denial is not that important since you already know that it will be the same as the ones given to you and your spouse. Denials of H-1B and H-4 statuses usually render the individuals illegal in the US unless they hold other status, and subject the individuals to a time bar of three years for remaining in the US illegally over 180 days from the date of denial (please note that the time bars do not apply to individuals who are under the age of 18).
