if someone moved from ecuador to argentina and opened offshore bank accounts and their ecuadorean passport was used to open accounts but like 5-7 years after they became an argentine citizen, would they have problems with the banks if they told them that they are the same person but with a new passport/citizenship? they opened the accounts after they moved to argetina as a legal permanent resident of argentina. they told the banks the truth, i was born in ecuador but live in argentina but they down the road became a citizen of argentina. would their new passport/citizenship be a problem if they can clarify like im clarifying right now? what would they need to do in such a case? lets say that an american citizen moved to canada a permanent resident when they opened those accounts they told the banks that they actually live in canada but several years down the road they became a canadian citizen, what then? someone from el salvador moved to paraguay and eventually became a citizen of paraguay. would such a transition be smooth or not? rsvp.
