Thankyou,

yesterday I was getting paranoid becasue I was unsure and I really want to come to the US as I have never been before and didnt want anything to hold me up or even worse stop me. my passport does indeed have the two lines at the bottom and also I have rang the local passport office who issued my passport and tehy have reassured me as well, they told me the worst that could happen if the passport was incorrect was that I would get a warning and would have to fill in a from at the airport to say the next time I travel to the US i would need a new passport. but at last pressure is off and i can start getting ready to travel now.

also found out today I have won a holiday to australia which is great
