Last Friday, June 28, 2019, the US government revealed that it had sent the final EB-5 rule to the US Citizenship & Immigration Services for publication in the Federal Register. This means that from the date of publication, the new rule will go into effect within 30, 45, or 60 days. For interested investors, this new rule will increase the minimum investment from the current $500,000 USD (since 1992) to either $1,000,000 USD or $1,350,000 USD. All petitions at the current level of $500,000 USD should be received by USCIS prior to the effective date of the new rule. If received prior to the effective date of the new rule, the $500,000 USD investment will still be considered as valid since the new rule is not retroactive.
