You could, for example, grant entry to programmers whose sponsors would be willing to pay very high salaries for them. Sure, you end up with false negatives (there are some great programmers who for some reason wouldn't be able to command those salaries), but hopefully it's not high enough to matter. Eg: 5% of great developers are in the US and 95% are outside. Assuming we have a false negative rate of 50% (a great programmer has a 50% chance of not being recognized as one), the policy would potentially let 47.5% of great developers in, which would potentially increase the number of great developers in the US by about 10x. The actual increase will be lower because not all of them will want to work in the US.
