我想问一下，论坛上 加拿大2015EE邀请后文件清单（Express Entry Checklist） 这篇文章里说工作信需要附上签名者名片，但是现在的说明里面并没有要求名片这一项：
(Applications for permanent residence programs subject to the Express Entry completeness check - Canada.ca)
The following documents are mandatory for each work experience declared:
- a reference or experience letter from the employer, which
- should be an official document printed on company letterhead (must include the applicant’s name, the company’s contact information [address, telephone number and email address], and the name, title and signature of the immediate supervisor or personnel officer at the company),
- should indicate all positions held while employed at the company and must include the following details: job title, duties and responsibilities, job status (if current job), dates worked for the company, number of work hours per week and annual salary plus benefits; and
- if the applicant is self-employed, articles of incorporation or other evidence of business ownership, evidence of self-employment income and documentation from third-party individuals indicating the service provided along with payment details (self-declared main duties or affidavits are not acceptable proof of self-employed work experience).
似乎是把名片去掉了。想确认一下，是否现在不需要附上名片？谢谢！
