Well, I'm not sure your husband will like the "
I'll let him figure that part out on his own" part regarding getting a job.
In terms of being around a lot of other Latinos, Gwinnett County is the center for that if that's what you're looking for. But some areas of Gwinnett have fairly decent crime, too. Further North of there however in Suwanee, you'll find a more family-friendly yet somewhat diverse area, not far from the International stuff, and not super far (relatively speaking) from Atlanta.
Powder Springs (where I live) is becoming more diverse. Has slid down a bit over the years but it's not a
horrible place to live. Latinos/Hispanics are accepted here so long as you speak English (obviously you do) and respect your neighbors (would apply to anyone). Home prices are generally cheaper here than many other metro area places. Commuting into the city is a bit hairy, though.
Smyrna is a diverse area with a number of Latinos and other mixed folks throughout the area (more expensive than the above two, though). Closer to Atlanta for jobs and city stuff. One option to consider.
