We moved to the US when my husband was transferred to work in the parent company's US office, and I spent 5 years at home unable to work due to the then visa situation. However, once I received my EAD I registered with an employment agency and worked temp jobs until I was hired on permanently. It took a couple of years before I found something that paid well, and it was sometimes difficult to be taken seriously by prospective employers who assumed we were expats who moved around a lot. But with persistence and the willingness to start at the bottom I found work, and its always easier to find a job once you're in employment.
I don't wish to burst your bubble but the FAA requires security type jobs at airports to be filled by US citizens, so it would be a minimum of three years before your husband would qualify, assuming that he is intending to apply for citizenship.
