I hold a B2 visitor visa and traveled to the US in August. after a lengthy secondary questioning ( about my employment status, reason for visiting, reason for needing six months and details of my girlfriend, subsequently contact was made to her to confirm my story) After which I was granted entry of six months, which I didn't complete since I departed the US two months later October. I would like to return to the US to suprise my girlfriend for our anniversary in February. Can I be eligible for entry into the USA if I want to suprise my girlfriend without her knowledge when I convey that to a CBP officer? Or would the CBP officer require my girlfriend to have knowledge of my visit?
