To be honest with you, applying through Nigeria during this period is not advisable. They've been pretty harsh on Nigerians applying through visitation (Tourist). You need to make a strong case why you'll be applying through Nigeria. Again, having a PR signifies that you've moved on and wanted to make Philippine your new home.
This is my advice to you as a consultant, apply through the Philippines, provide them your financial status back in Nigeria. Are you applying alone or with your wife? Is your wife working and have good ties in her country?
If you have any business in Philippine, your marital status and proof etc....
