The chance of any major/legacy airline in the US hiring a temporary Visa pilot is not 0%...its about negative 1000. No chance unless people stop wanting to go to majors which will never happen. They will literally hire citizen cadets directly to the right seat before they hire an E3. Regionals will probably hire you and give you a job right up to when they furlough/go out of business/don't want you anymore, which a lot of guys have found out the hard way the last 3-4 years it seems.
