Immigration and Asylum polygraph (lie-detection) testing is used nationwide for Federal Immigration Court hearings; Federal immigration judges and Hearing Officers are typically very accepting of polygraph reports as supporting evidence thanks to the Federal government being the biggest users themselves of polygraph!
Polygraph expert John Grogan of www.ImmigrationPolygraph.com has taught many PEOA members and others the excellent specialty of 'Immigration Polygraph' including how to market to the number one client for this: immigration attorneys. Since immigration & asylum applicants have the 'burden of proof' in these court matters, a polygraph exam can cut through years of red-tape and delays.
