In order for a foreign national to be eligible to enter the United States to visit, live or work legally, he or she must be admissible or else qualify for an immigration waiver. Certain factors could make an applicant inadmissible such as prior immigration history, financial situation, medical history or criminal history. If found to be inadmissible, an applicant for admission to the US may be eligible to file an immigration waiver to overcome the inadmissibility. To be successful, the immigration waiver package must prove that extreme hardship would be suffered if the foreign national were not allowed to immigrate to America.
