Unfortunately that's not true. It is not easy even for strong programmers to polish up on Leetcode, find a new job, get a written job offer, have the new employer to file for an H1B transfer, and get an acknowledgement from USCIS all within the 60 day window. The 2021-2022 job market was an aberration where anyone with a pulse could find a programming job within a few weeks.

Even in the best case, as the 60 day deadline gets closer you also have to plan for the contingency and start planning how to uproot your life. Pack your belongings, sell your car, plan to take the kids out of school for at least the current school year. Even if you get the H1B approval a few days after you return to your home country, visa stamping can take months so you have to plan for an extended absence and the good possibility that you won't be able to return.

Sure we can say that this is exactly what H1B workers signed up for when they came to the US and it is true that no one goes into this blind. However it is not a pleasant situation to be in, and the fear of facing this, especially in the kind of job market we saw in 2023, takes its toll on families.
