No one can guarantee that you will obtain a Portuguese residence permit by investment. If someone makes such a promise, the offer is almost certainly fraudulent.
To reduce the risk of rejection to 1%, Immigrant Invest conducts a preliminary Due Diligence check. The investor’s documents are reviewed by a certified Anti Money Laundering Officer who is an expert on Due Diligence in different countries. If they find a potential weak point, we will look for an alternative solution to circumvent or avoid the problem: for example, we may add additional documents for submission or recommend another program.
