0jenifer0: IMO, personal presence is required for pc - atleast in India. If you require a pc from abroad, your first step should be to visit that country's website and get that info from there. If its not available there, get their phone number and call them up.
I do not know what you mean when you say " I dont have any requirements to show here in the Philippines to obtain that Policee Certificate in the Embassy". Do you have a passport with the visa and/or entry - exit stamp of the country in question? Most likely, that is all you would need for the embassy.
I would also ask my friend , to inquire from their end as to if it is possible for them to directly get the pc. compare both ways and take the shortest route.
From which countrty do you need a pc, if you dont mind me asking.
