I9 -

概述

I-9 表格(正式名称为“就业资格验证”)是美国公民及移民服务局的表格,用于验证美国所有带薪员工的身份和合法工作授权。

该模型最多可以提取 67 个字段,您可以根据业务需求自定义。

特殊性

该模型会自动检测以下数据:

  • 员工的名字、姓氏、中间名首字母、地址、出生日期、SSN、电子邮件、电话
  • 公民身份
  • 雇主或授权代表审核和验证:文档标题、颁发机构、文档编号、到期日期
  • 重新验证和重新雇用:名字、姓氏、重新雇用日期、文档标题、文档编号。

Extracted fields

备注:

If you are using using public endpoints, such as https://du.uipath.com/ie/invoices, all fields are available. However, if you are using custom-trained extractors, the availability of extracted fields is dependant on the version you are currently using. You can also check the list of fields and types on any endpoint in the /info/model object. To access this, simply add /info/model to any endpoint, like so: https://du.uipath.com/ie/invoices/info/model. For an enhanced reading experience of the fields list, it's recommended to install a JSON viewer extension in your browser.
