An individual in a Regional Center investment must qualify as an accredited investor who either has $1,000,000 net worth, not counting his/her residence, or has earned at least $200,000 in each of the last 2 years.
I agree with Silver Surfer. I believe you are asking a securities law question, not an immigration question.
In order to be eligible to invest in an EB5 Offering that is relying on the Regulation D exemption from registration, you need to be an "accredited investor." Generally speaking, that means you must have either (1) individual net worth, or joint net worth with your spouse, that exceeds $1 million at the time of the purchase, excluding the value of your primary residence OR (2) annual income exceeding $200,000 in each of the two most recent years or joint income with a spouse exceeding $300,000 for those years and a reasonable expectation of the same income level in the current year.
Based on the annual income figures you set forth above, I believe you would qualify as an accredited investor.
As long as you have evidence that your income was lawfully created, and that the source of your investment is from that income, then you may be able to satisfy the relevant source of funds provisions of the EB-5 law. More information would be needed to give a definitive answer.
Additional information may be needed in order to fully answer your question. However, if you have documentation to support your income stream and your savings throughout the years, you may be able to support the evidence of legal source of income.
It appears that you are really asking if you would meet the SEC Regulation D qualifications as an accredited investor. That must be discussed with a lawyer and/or CPA who knows the SEC regulations and can examine your paperwork on an individualized basis.
