It was perhaps the most insanely stressful period in my life. You cannot begin to fathom the desperation that comes with it. There is literally a ticking time bomb until the country is like “whoops, looks didn’t work out for you buddy. Just pack your bags and leave your life and go home. Bye!”. I think of myself generally as a rather carefree person but I couldn’t sleep at night because there was the very real chance that I would just not get a job in time. I wouldn’t wish this on anyone.
I basically did what the author describes... cast a pretty wide net in my job search. Couldn’t make it into the FAANGS but got another job just in time. The timing was pretty insane though. And as a person still on an H1B that worry is always on top of my mind, although as a fairly experienced engineer now, it is somewhat less intimidating.
The other thing that Citizens May not realize is that CBP can stop you from entering for any fucking reason whatsoever. Which is what prevented me from buying a house and making other long term investments.
