Hi Desfer
It's ok, when CIC-London asked me to send the documents regarding assets, I've just presented our bank statements in the Philippines, ok lng kahit philippine pesos basta ma-meet mo ang requirements nila regarding proof of funds.. Since nasa Ireland ka naka-based, mas madali mg-process ang London compare sa Manila. Anyway it's your choice naman so better to check their website para up to date ka lagi..
Hindi nila acknowledge ang credit card, it should be a savings account statements, could be from the Philippines or account mo dyan sa Ireland.
Hope this helps.
