Self-petitioning an employment file is a great way to apply for a green card; however the petitioner must qualify.
Applicant/petitioner must show through evidence that waiving required labor certificate is beneficial to the national interest of America.
Outstanding researchers & professors, extra ordinary abilities & candidates for national interest waivers are among those who may successfully get their green cards without having an employer-sponsor.
The burden of proof is on the applicant. He must show through convincing evidence why he would meet the criteria.
A history of his past experience, recommendation letters from peers, review letters from industry experts, publications, a current job offer may all be used to show the importance of one's related field & the impact of his work on the field.
One may qualify to apply for multiple ways of receiving a green card; consulting a legal expert is the key to success.
