I got H1b visa stamped on Nov19th 2015, travelled to US on March20th, landed in chicago port of entry. There the customs and immigration people verified some details and they have deported from chicago airport. They cancelled my visa and mentioned a clause that i can't enter US for the next 5 years. Is there anything that i can do now? My petition(case number) is still active, can i take one more employer and get stamping done?
