洗钱在美国可是件大事，2百万，一定会查得到

Treasury Department, FBI, IRS will be all over you. You will face multiple felony charges, including, money-laundering, mail fraud, tax fraud, etc. Convition of any one of them will lend you in a federal penitentiary. As this will certainly be a crime of moral turpitude, you will lose your green card or be stripped off your citizenship and for sure, you will be deported (after jail time).

You are not talking about a fine by the IRS. You are talking about commiting crimes in this country.
