try to get married in philippines and ask her to change her passport using ur surname and she can come back here under tourist visa without the need of NOC since system wise it'll be new details. if ur eligible to acquire family visa status, same way u'll be needing letter from your company which as per you, boss is not approve. if she will look for new job and working visa, same way NOC might be needed coz in finger printing, old details will show. so even she come here, without that letter, she won't be able to stay.

there's a lot of way and options but you just really need to seek help to right people.

good luck!
