if someone who was born in el salvador but who was living as a greencard holder only in the usa, decided to legally change their entire name on their greencard, texas drivers license, el salvador passport issued at the consulate of el salvador in houston, texas, ect.......... but one day traveled back to el salvador and over there bought a house, got a government id, drivers license, ect...... but under their old name and from that point on decided to open offshore bank accounts but under that old name. the banks sent them debit cards to el salvador and from there they returned back to the united states where they are legal permanent resident. how would uncle sam discover them using these offshore bank debit cards to undeclared offshore bank accounts to a person with a different name in another country that in fact is the same person? i know that oecd, tiea, aeoi, crs, cra, fatca, whatever you wanna call it, ect............. are now sharing information on a global scale. if they were to use that debit card from an undeclared offshore bank account which fatca or anyone else know about, how might they risk getting caught eventually? can anyone please tell me. thank you.
