An I-485 is "Application to Register Permanent Residence or Adjust Status". You can only apply for an I-485 after 5 years of residency. That means after 5.5 years you may freely change jobs - to a similar position. For those 5.5 years you're still vulnerable to discriminatory treatment. I'm not sure if "similar position" means you could form your own company.

If I were 21 again - no brainer. Unfortunately I'm nearly 30 and would be setting myself backwards if I did it now. It makes more sense to spend time establishing myself locally and using that to put myself into a more favourable negotiating position with a sponsor in the future with respect to emigration. Alternatively I may choose a country with more sensible emigration policies (e.g. Australia, UK if they reinstate their highly skilled migrant quota) and then the US loses out.

As far as I can tell, you can submit the I-140 immediately after arrival, processing takes about 6 months if you don't apply for "premium processing". Then you can apply for I-485, which then needs to be pending for 6 months - ie. you're only stuck for a year. But I could be wrong?

Hmmm if that's the way it works that's a very positive change, although it's very different from other countries (where you can only apply for permanent residency after a number of years of actual residency) so I wonder if we're seeing the proper picture here. Finding simplified requirements is pretty difficult.

Your first link does indicate that the backlog for EB-3 category applications is 6-9 years. So in that time you presumably must be working and wouldn't e.g. be able to start your own company (which is something I'd want to do by age 35), and you'd still be at the mercy of companies who know you're an emigrant so they can pay you less. It doesn't look like you can apply for residency in the EB-2 category as a programmer unless a masters or above is a requirement for the job (i.e. Google is hiring you).

Overall the situation for older migrants is still not very good and while the US would be my first choice it still seems better to emigrate elsewhere or to wait until I'm more established and I qualify under a category with a much shorter backlog (after which it's another 5 years for naturalisation, whereas in other countries you're looking at 5-7 years TOTAL).

One serious potential problem: apparently the old employer can revoke your I-140 (if you change companies) and you lose your priority date if that happens. [1] Also all of this assume your sponsor is going to file the I-140 on your behalf. What if they promise to do it and then don't? You're still at their mercy.

Thats right, however on your second link you can see the dates for China, India, Mexico and Philippines are backlogged for many years, as these countries are the source of most immigrants.
