Depends on how many jobs are created overall and where he falls in the hierarchy of the 25 investors when filing his I-829. For instance, if he is investor 13 to file the I-829, and the project has created 150 jobs, he is probably okay. But if he is investor 15 and the project only creates 130 jobs, he is likely to have problems with his I-829.
What happens if an investor makes an investment in a regional center and the development falls short of the number of jobs originally projected? He is one of 25 other investors.
Generally, the jobs created go to the first investors in the project who are ready to file Form I-829 petitions. If the investor is in a regional center project, he may be protected by an economic methodology that shows the creation of indirect and induced jobs.
