Your answer got cut off but an adjustment of status would require her to currently be here legally. Her visitor's visa was expired before the adjustment of status application was submitted. I don't think you can use that. I'll link a friend who has a better understanding to your question.

Unfortunately, it is not true that she is required to be here legally for her term. Here's all you need to do. Contact the powers that be and state that you are a US citizen. You can quickly and easily make your wife a lapr. They have a pretty simple program for this. If you've got kids together, or if she has kids that are US citizens, then it only gets easier. I'm just happy to see people other than Mexicans immigrate here. Even though they denied her petition, you can just resubmit it. Worst casem just file for an extention. Mexicans cross with these all of the time and they're good for a year. The fee is low, incidentally. By the way, if she goes out of status and you get caught with her by the wrong agent (or the guys at the port), you're smuggling an illegal alien and your car can be seized as an instrument in transportation and furtherance of an undocumented/out of status alien. Every US citizen in the car is then the smuggler, and can be arrested. None of it would go to prosecutions, at least not in Arizona, and the agent would spend hours on the whole thing, but it will ruin your night. You've got plenty of time, talk to the POE if you don't know where to start. I, personally, was instructed by my sup to release an illegal Mexican out of our front gate because she only had 4 or 5 days left until she met her 5 year mark. And her paperwork was in for her legal resident card. Even if we held her, it would have taken longer to remove her (due to the complexity of the situation..year right) than for her to get her lapr card. I tried to get a denial for her petition but that was rejected, too. Thanks liberals...
