急！！急！！旧金山转机7小时间隔,我怎样能出机场?

我将从浦东飞往旧金山SFO机场,早上8:25到,转机要到3:25,中间有7个小时时间。想在这段时间里去渔人码头给朋友带点东西，从GOOGLE MAP的线路来看，来回要2个多小时。如果抓紧时间的话，我觉得还是可行的，大家有什么建议？
主要是我没有在转机中出过机场，不知道可不可行？具体要怎样操作？我的两个航班都是UNITED的，不过不是同一驾飞机，谢谢 ：）！！！

请再问一下. 我持有的是学生VISA一年的,为什么一定要有绿卡才能出机场? 照道理到了SF就是进了海关啊? 各位的回答把我搞糊涂了,谢谢~

P。S：是金属妖精的锡像，我只有在那里有看见过：）

pal,

1. u take international air to enter sfo when u arrival the boarder.

2. u'll transfer domestic air to ur destination.

3. during these 7 hrs, u have to do:

enter the boarder; pick up ur package; find ur next plane ~~~

now u wanna to buy something, then u have to make it after when u pick up the package.

practically, yes, u could.

my suggestion is renting a car to get there from airport. but u get to be sure u have a drivers license and know the path.

有什么东西需要从渔人码头带？

转机过程中不能出关的。。。除非你签证上说你要再LA出关

如果你仅仅是路过旧金山.. 而你机票最终地点不是旧金山的话.. 您很可能不能出机场.. 因为我从中国前往纽约的时候.. 中转站是底特律.. 但是在底特律只能在机场里面的免税店逛.. 不允许出机场的.. 如果你的终点站是旧金山.. 那你可以在机场直接乘坐BART类似轨道列车.. 很便宜.. 或者您可以租车.. 都在机场那就有.. 渔人码头风景胜过您能带的特产.. 当然最棒的是那得螃蟹.. 您值得去尝试一下.. 如果没有什么特别要买的.. 在旧金山国际机场里面的免税店您能买到很多东西.. 而且机场时免税的.. 比起来在加州市面卖的都会便宜很多.. 最后祝您旅途愉快``

If you need to save money, you could take BART (about $5) to downtown (Powell Station, about 30-45 minutes) from there you could take cable car (which is very popular among tourists, 10 minutes waiting time, 20 minutes ride)) to fisherman's wharf. The disadvantage is that you need to wait for BART train and cable car. A round trip will take you more than 2 hours. if money does not matter to you and you need to save time, you can take what we call "door-to-door" van, which is small minivans and you can tell the driver to drive you all the way to fisherman's wharf (takes maybe 30-40 minutes). The cost is about US$20 one way. To go back to the airport,...If you need to save money, you could take BART (about $5) to downtown (Powell Station, about 30-45 minutes) from there you could take cable car (which is very popular among tourists, 10 minutes waiting time, 20 minutes ride)) to fisherman's wharf.

补充问题: 这是出入境管理的责任问题. 拿到签证后你的入境地点, 应该在你的学校所在地. 那个地方的海关才会办理你的入境手续, 才允许你进入美国. 按照美国人的思维, 你应该是先去学校安顿下来以后才有心思到别的地方去参观游玩. 这也有助于移民局对外国人进行监控追踪. 如果你随便找个地方进来了, 移民局还怎么管理你? 如果旅游签证的人说是要去纽约玩, 然后跑到SF入境, 你是海关人员的话你会怎么想? 如果有绿卡, 海关才不用担心你是黑户, 才会许可你随意进出海关机场. 你现在有美国绿卡没?
