You must report gifts you receive from foreign persons of more than $100,000 per year. Gifts are never taxable to the recipient.
If you are a US taxpayer (citizen, green card holder, or resident alien) you must report gifts you give, in excess of $15,000 per person per year. Gift tax is not owed unless your lifetime gifts and estate are more than $11 million, but you must file the report.
However, banks are required to report all transactions over $10,000, so the IRS will get a report of money coming in and going out. They may investigate. If it turns out that these transactions have an improper purpose (such as, the money is coming from a country that is under sanction, and the Dubai account is a workaround; or the money is coming from some other improper purpose) then you could be prosecuted. If the transactions are proper and you are not disguising an improper purpose then there may not be legal consequences but the investigation itself could be intrusive and difficult.
No one on this board can give legal advice. You may want advice from a qualified attorney before taking on this arrangement.
