美国Employment-Base123数据汇总,积压和等待时间分析

    在NIU和广大网友一起努力下,我们把Employment-base的历史数据(EB123)都集中汇总到了一起,做成了一个可以互动的dashboard,点击下面的网址即可
http://stats.niunational.org/

目前该dashboard的主要功能有

  1. 查看2007-2020年EB123的历史排期
  2. 查看USCIS官方网站pull下来的过去10年140的申请approval数据(分国家和年份的)
  3. USCIS官方网站爬下来的过去10年绿卡发放信息(分国家和年份)
  4. 全部的140/485统计
  5. 绿卡需求和积压的分析。用户可自行输入140:绿卡系数,计算目前和历史某一时期的backlog数量,方便大家理解排在自己前面有多少人
  6. 绿卡排期的分析(beta),用户可自行输入家属系数,以及spillover的预期,预测自己pd的等待时间

该dashboard里面所有的图表均为动态生成,用户可通过图例自行选择不同的数据做可视化。下面列举了一些例子

  1. 这个Backlog数据不知道是如何算出来的?移民局在2018年5月和2020财年前两个季度都公布了在等排期的140数量

    https://www.uscis.gov/sites/default/files/document/data/EB_I140_I360_I526_performancedata_fy2020_Q1_Q2.pdf
    根据这些表里面的数量和网站上给出的140:GC比例,2018年5月时的Backlog应该是16617x1.4+3948 = 27212(27211.8),但是网站上那时候的Backlog已经是47703了。用同样方法就算2020财年的两份报告得出来的分别是50254(50253.8) VS 63920 和 51123(51122.4) VS 68815。所以我比较好奇网站上的Backlog数据是如何算出来的?

  18. yet some of the time it's the main choice. Terminating somebody is generally an unsavory circumstance, yet you really want to confront it as something that will definitely occur in your association, and before you even consider letting an employee who isn't living up to the assumptions of the business go, földmunkagép szállítás Europa-Road Kft.
