如果美國有學校肯收我,冇學生驗証揸旅遊驗証是否可行呢.聽人講可以到時揾律師轉做讀書身份.
係唔係真的.

yes you can try.. but then it will become very difficult for you to get visa to re-enter into US once you leave its border (i.e., summer holiday in hk)

but where you gonna study? college or what?
If you go to college, probably you need a I-20, too.

I have a question , why do you need to 跳飛機? Why don't you just apply online and get the visa in Hong Kong before heading to US?
