What is the easiest way for a Vet Tech to get a work permit to work in the USA?

Answer

Work Permit in US is the Employment Authorization Document (EAD). The Form I-765 application offers the benefit of receiving an Employment Authorization Document.

The I-765 application can be sent individually or with the I-485 form. For the principal applicant, the EAD should be issued by the USCIS as soon as the preliminary screener determines the eligibility, unless the applicant is clearly ineligible for the adjustment of status, in which case the application should be routed for an expeditious denial.

For dependent applicants, employment authorization (Work Permit ) may be issued as soon as the principal applicant case is documented, provided the dependent applicant has submitted satisfactory evidence of the relationship.

Therefore, there is NO "easiest way" to get Work Permit. To work in US, generally, you need to be hired by an US employer first, then apply for H1B visa (if you are a Vet Tech ) to work in US legally, and ask your employer to apply for PERM labor certification for you to get Green Card.
