签证 【求助】中国公民在温哥华签证

[mus.d_robin]

大家好，我是中国公民，在温哥华读语言，现在被一所美国大学录取后准备在温哥华直接签证。 我已经预约08年7月30日的。
问题1：DS-156表格的中文电码还需要不需要写啊？是用手写吗？
问题2：DS-157的表格是用手填写还是用电脑打？
问题3：DS-158的表格是用手填写还是用电脑打？
问题4：当我预约好后有个CONFIRM，他们上面写着
All visa applicants are now required to submit electronically completed applicationforms.
Hand-written forms will no longer be accepted. If you appear for your
interview with a hand-written application you will be turned away and assigned
another date for your interview. You must complete the electronic form on-line at
http://evisaforms.state.gov, print out the entire form including the third (barcode)
page, and bring it with you to the interview.

这是指所有的DS表格还是只是说DS156的？

问题5：还有他们写visitors to Canada are strongly urged to apply
for U.S. visas in their country of residence.
强烈建议回国签，，在温哥华签F1的咋样啊。。。到时候又给我拒了就糟糕了。。。

谢谢大家帮忙啊 ！
着急啊！
