National Interest Waivers
A national interest waiver allows immigrants to bypass the requirement for labor certification to enter the United States to preserve the “national interest.” This can greatly cut down on the wait time to get into the U.S. provided that you meet the requirements for a national interest waiver.
For most temporary visas, applications require a labor certification and the proof of a permanent job. Labor certification can be difficult to obtain. The certification must be granted by the government after your employer proves there are no qualified Americans who are willing to do the job When this has been accomplished, you have labor certification, which allows you to apply for residency to live and work in the United States.
The national interest waiver bypasses the labor certification process completely, but you must prove several things to gain entry. More than anything, you need to prove that your presence to the United States is paramount to the country’s progress and, if you are kept out, it will be detrimental to progress.
