Hi there and welcome aboard Filipino UK

You don't mention which type of visa or where you applied from so I guess it's a settlement type from Manila.

If you take a look here at the UKVI visa processing times
you'll see that most applications are processed within 60 days, however some may take longer.

Don't forget that there's been a significant number of holidays and non-working days during that past couple of months which could have impacted on any enquiries being followed up by the Manila Hub

Those specific enquiries could be related to any of the key issues, often relating to your sponsors Financial position or any relationship issues.

Do you have happen to have any immigration history that may need additional checks?

Fingers crossed for a positive outcome
