You could be, but it depends on the USCIS field office. The requirement is that you reside in the field office's jurisdiction and that's open to interpretation. I was able to DCF in Mexico on a tourist visa, but I had been living there full time for 4 years. Mexico allows visa runs, so to renew my visa I simply had to leave and re-enter the country.
Once I learned about DCF I contacted the USCIS field office in Mexico City and they told me that I likely qualified. It was easy for me to prove that I resided in Mexico as I had built a life over 4 years. I had a lease, bills, passport entry stamps, etc.
Be sure to contact the Manila filed office, you can find their contact info here: https://www.uscis.gov/about-us/find-uscis-office/international-offices/philippines-uscis-manila-field-office . They also have more info regarding filing the I130, including additional residency evidence you can send. Here's an excerpt:
Yeah you qualify. I was here since last Aug after our wedding on a tourist visa. I didn't get changed to dependent on my husband's work visa until Jan or Feb. Although once you leave ph the six months start over again, I believe, so the Hong Kong route may not be the best road for you. I think it's just bc of the tourist visa though. Maybe someone else can confirm or correct my assumption. Good luck
