加拿大网签的两个文件

两个要上载文件，passport or travel document 和 travel history 所提的要求，太类似了！
感觉travel history里面就是把要求更详细的说了一遍。
Document: Travel History
You must provide information on your valid visa from the United States as well as previous travel history. This can include copies of
• your previous passports and/or visas (used within the last 10 years to travel outside your country)
• entry and exit stamps
• study and/or work permits that indicate your duration outside of your country
• expired or valid visas
• boarding passes
还是说的passport的各种细节，这到底该弄个啥样的文档来upload呢？
先谢谢各位大侠～
