In (some?) other countries work visas are not tied to employer but rather job category, and the length of time waiting for permanent residency is usually 2 years. In the US an H1B can be transferred once you reach the portability threshold if you can find another employer, and depending on the country of origin you can be waiting for permanent residency (green card, not citizenship) for 2 decades. An L1B is tied to an employer and you're effectively illegally in the country as soon as you're laid off. In practice the government gracefully gives you a week to completely uproot your life and get the hell out. I was lucky, I went from arriving in the country to receiving citizenship in ~10 years, but the 4 years trying to get permanent residency were the most stressful of my life, and being spared by layoffs did little to help. Even being privileged knowing you can go elsewhere, and fully open eyed about the situation, it still sucks.
