Employment verification has become a crucial task of the job screening process as thousands of illegal immigrants cross the deserts and murky waters to come to work in America.

It is the responsibility of the employers to ensure conduct employment verification on all immigrants and to ensure that they have the necessary papers to work in the United States.

Employment verification for an applicant is often done after other pre employment checks are done. Usually, employment verification is the last stage in job screening.  Before this stage, employers usually conduct background checks and criminal background checks on the applicants.

The Immigration Reform and Control Act made all U.S. employers responsible for employment verification. Employers need to ensure that all forms for eligibility to work are completed and signed by the applicant.

Immigrants to the United States are allowed to work in the country only after they receive an Employment Authorization Card from the US Citizenship and Immigration Services. Employers as part of the job screening process need to ensure that immigrant applicants have the necessary papers to work in the country. If selected for a post, employers need to conduct an employment verification check and submit the papers to the USCIS.

Sometimes, a U.S. employer may hire a new employee who doesn't physically come to that employer's offices to complete paperwork. Even in that case, employers need to ensure employment verification. Agents such as notaries public, accountant, attorneys, personnel officers and foremen may be authorized to carry out the employment verification and file the necessary paper work.

Employment verification for an immigrant is not limited to ensuring that all paper work is complete and in order. This is just one step in the employment verification process. Extensive background screening and personal background checks are conducted on applicants.

Many employers conduct social security background checks for immigrant applicants. This has become more common since the terrorist attacks of 9/11. By conducting social security background checks on an individual, an employer can determine if the person has an alias and whether there is any criminal history.

The responsibility of employment verification for an immigrant falls on an employer. It is the responsibility of the employer to ensure that all paper work is in order and that the applicant is eligible to work in the country.
