Is it legal for a condo company to get the original copy of oath of allegiance? Philippine consulate here in NY told not to give original documents?

I am a dual citizen (PHIL-AM) living here in NY USA. The condo unit company told that they will not be able to turn over a fully paid unit unless I submit my original oath of allegiance. I only have one copy of those and I even inquire the Philippine Consulate of NY and told me not to give original copy, just a certified true copy but the condo company told that they do not accept if not the original copy. The Philippine consulate told to provide them a contact person and they will email this person but unfortunately they never reply at all. It is just hard to be far from Philippines dealing with this kind of issue. I want my unit to be turn over. Your help or any lawyer recommended will be truly appreciated
