我和舍友现在在申请psw转entrepreneur的签证，下面是总结出来的问题：
第一个问题是29页：
Does the other member of your entrepreneurial team currently have leave to remain in the UK?
No --Go to G3
Yes --Please give the Points Based System reference number of your entrepreneurial team member:______________
我们俩人目前都是Tier 1 Post Study Work, 都在UK，应该选yes，请问这个Points Based System reference number要上哪里找？我把uk border agency寄来的信弄丢了，那我要去上哪找呢？网上怎么查都查不到
第二个问题是31页：
G10. The applicant must complete the following table to confirm the documents provided to demonstrate the funds available for investment.
在下面的表格里，是只要填我的资金，还是要把另外一人的资金也填上去,并提供他银行相应文件？
第三个问题是34页：
G21. The applicant must demonstrate that their main business activity is at graduate level.
我们两人都在公司上班，都符合要求的职业，这里需要提供什么证据来证明吗？
第四个问题是51页：
For applications submitted after 14 June 2012, applicants in the United Kingdom seeking further leave to remain must have at least £900 of personal savings which must have been held for a consecutive 90 day period prior to the date of application.
比如说目前我有25,000镑，我的team member有25,000镑，如果加上这个£900的personal saving，是否每个人的帐户里要至少有25,900的金额？
求各位大虾拔刀相助，谢谢！
