I understand this might not be the right forum, but..
A couple of months back I was flying from Finland (where I live and am citizen of) to the US to spend time with my girlfriend, who is a US citizen. Upon my arrival in Seattle, at the airport I was taken in for secondary inspection and questioned for hours, after which I was told I have been found inadmissible to enter the United States. The section 212 (a) (7) (A) (i) (I) is mentioned in the papers I received - how the actual questioning went was that I got pulled in, questioned about my motives for entering the US - and as I answered I was going to be with my girlfriend for a little under 3 months (so I could stay under the Visa Waiver program) the CBP officer called her and her mother whose place I would have been staying at with her. We all feel we were given differing information by the CBP officer and this lead to my entry being denied.
The CBP officer in question suspected me of intent to work in the US illegally, and when calling my girlfriend's mother he pressed her to say she would be willing to hire me if needed (which she thought was what he wanted her to say, an unwise move of course) and based on this, the CBP officer sent me right back home and my right to participate in the Visa Waiver program was removed. I was not given a ban or anything of the sorts - the officer kept telling me I should consider myself extremely lucky he did not bar me from ever entering the US again. All throughout my questioning at the airport he also repeatedly told me to stop lying although I had just taken an oath to speak the truth and nothing but the truth. Is there any way I can complain about my treatment and denial of entry for no evident reason? Thanks.
