Hi, what we ended up doing (after a lot of research and talking to others who are also applying / have applied from lebanon) is that we kept the USD in the bank, we added the missing amounts in LBP and got a bank statement for the past 6 months. Turns out most Lebanese banks don't give bank letters in the first place, they only give statements of accounts. Official rate is still 1,515 so you should be fine for POF if you have a mix of USD and LBP at the bank that add up to the funds required by IRCC. We are also saving up money at home in cash which we will actually take with us to Canada, because right now we can't be sure that we can transfer anything we have in our Lebanese banks or when.. This is what everyone is doing so let's all hope for the best.
