If you have been 100% legal when in the US, you should be OK.
Obey the law and don't come back to the US until after you have gotten your visa at the US Consul.

Assuming that there were no misrepresentations to the Consulate when you initially applied for a visitor visa (a question on the nonimmigrant visa application form asks about family members in the U.S., for example), the Consulate should issue the immigrant visa if you are truthful on the forms to be completed as instructed by the NVC.
I agree with Attorney Capriotti that you should not return to the U.S. again on your visitor visa.
Not so fast... Did you say that your husband already filed adjustment of status applications? Is that what you meant when you said he paid the AOS and the immigrant visa processing fee? Why not just stay here and wait for them to get approved? The numbers are current in family 2B preference. As long as the decision to stay and adjust was made AFTER you arrived in July you don't have preconceived immigrant intent. You should talk to an expert about this, but I'm thinking you should just stay here and finish processing adjustment with USCIS and forget about consular processing with the dept. of State.
