What is the difference between an I-526 and an I-829 petition?

Re: The I-526 is the form filed along with the supporting documentation for the initial EB-5 petition. It will lay out the business plan regarding the new commercial enterprise, how the 10 jobs will be created, and document the lawful source of the investment funds. Assuming it is approved the investor and his/her family receives conditional permanent residency.

1 year and 9 months later the investor's attorney then files the form I-829 to remove the conditions on the permanent residency (along with more supporting documentation). At this stage the investor must show that the 10 jobs were actually created, that the business plan was executed, and that all of the money is still invested in the commercial enterprise.
