I agree with all the points here and would advise same i.e. maintain your funds till the time you land if possible. To answer the question POF check is done at the eligibility stage. However, we have seen atleast two cases on this thread where people were asked to submit updated POF.Time and time again, people have said that it is best to maintain the funds till approved and even till after landing because it is clearly stated on their website. I understand that it can be difficult to maintain that huge amount of money for a loong time, in our case 6months or more especially when you have needs, bills and things to use money for. But if you can do your best to get the money back to the minimu it would be great. Some people have been asked to show updated statement of account. Someone was even asked to show statement of account from AOR till the date of the letter sent. So its always safest to maintain it so as not to take any chances
