Sigh: it'd be nice if we used the same system of measurement as ~the rest of the world. Some history: the Metric Conversion Board was abolished by President Reagan in 1982. Executive order 12770 was then signed by President H. W. Bush in 1991, but has only had partial effect.
President Ford signs into law the U.S. Metric Conversion Act of 1975, which will guide the gradual replacement of the English system of measurement with the metric system in the United States.
@David_J_Bier @AttyStevenBrown @immigrationgirl @gsiskind & the rest of #Immigration twitter, hope you're able to raise awareness if you're seeing this too 🙏
Is the US visa website for new DS-160 applications broken right now? Here's what I'm seeing:
URL where I'm seeing the error: ceac.state.gov/GenNIV/default…
The "Start an Application" button is grayed out. When I click on a location in the dropdown, the page redirects me to an "Application Error".
@StateDept @TravelGov I filled out the 'Contact Us' form to report this error, but couldn't attach the screen capture video

@immigrationgirl Remember to check that the border officer correctly filled out your I-94! If it's incorrect (happened to me once), you need to go and fix it 🫠 #just #GCbacklog #things
A squirrel is quite a reason to replay a point 🐿️
@paulg I don't think people in the US tourism business realize how much money a far more complicated process than this has already cost them.
The U.S. visa system is broken, with year-long wait times at many consulates just to get an interview appointment @IFP has a new website tracking processing delays at the State Department
Here's what out-of-control bureaucracy looks like. The Green card application today (all those pages on the left) v. 2003 (those 4 pages on the right). Understand this: We got no new laws during this time. We just got new bureaucrats cato.org/blog/uscis-has…
Since 2004, guest workers have to travel abroad to renew their visas Reviving domestic reissuance—and expanding it to include students—would ease the renewal process for visitors while lightening the caseload at consulates Latest from @dkaushik96 and me: progress.institute/domestic-reiss…
