数据有很大的问题。机构的文件有,可以用这个搜索, The Long-Term Stay Rates of International STEM PhD 其中的内容 Long-term stay rates are high. As of February 2017, roughly 77 percent of the more than 178,000 international STEM PhD graduates from U.S. universities between 2000 and 2015 were still living in the country. 2. Stay rates remain high even among older graduates. Since 2000, at least 65 percent of every year’s graduating class has stayed in the United States, and since 2004, no graduating class has had a stay rate below 73 percent. 3. Stay rates are similar across STEM fields. Though stay rates for different fields vary across individual years, no one STEM discipline has consistently higher or lower stay rates than the others. 4. Chinese and Indian nationals account for nearly half of all international STEM PhD graduates in the United States, and most stay long after graduation. In February 2017, approximately 90 percent of Chinese nationals and 87 percent of Indian nationals who completed STEM PhD programs in the United States between 2000 and 2015 were still living in the country, compared to 66 percent of graduates from other countries. Due to country caps on green cards, Indian graduates have more difficulty obtaining permanent residency than other international students. 5. International STEM PhD graduates follow a similar path through the U.S. immigration system. The plurality of graduates who completed their degrees between 2004 and 2011 had obtained permanent residency by February 2017, and among those who graduated before 2004, nearly half had become naturalized U.S. citizens

在车库外面装一个 Tesla 的充电桩,设备$600, 人工$3800。 3个工人慢悠悠干了一天,拉一条220V, 50A 的线,装一个分电箱。人工真正贵。

@@franciscoantonio314 我们这个区房子比较贵。线要从 crawl space 走比较长。$3800 包括所有的人工和材料费。$500 is for the Tesla parts. This is considered normal price for my area after talking to friends.
