Consulates may seek additional documentation and you may have to produce them. The additional documents could range from title/mortgage documents showing property owned to recent bank statements showing the availability of immediate funds. As mentioned in an earlier answer to a similar question, more is always better in these instances.
The lack of education may pose a problem in the Consulate’s assessment of the future prospects of your husband finding a job in the U.S. The Consul may perceive the lack of education as a disqualifying factor from that point of view. Demonstrating experience, skills and the ability to find a job in the U.S. is imperative.
I strongly recommend that you collect and produce documentation of financial ability to support yourself and your new husband in the U.S.
