Hello - can anyone help?

I got married in the Philippines in October and my wife gave birth to our daughter in December. We registered the birth at the city hall, however the NSO in Butuan say that the birth certificate will take 6 months- One year to arrive!! Is this right? I was hoping to bring my wife and daughter over to uk on a spouse visa in August. But we can't apply until my daughter has her passport, which will be dual?

My wife has just applied for her passport.

I need the birth cert to arrive before JUly.

Should the birth certificate take this long?
