Good luck, having just gone thru K-1, that is what I would suggest unless you plan on staying in PHl a fqir amount in the next 2 years.
it is a long and tedious process.
my fiancee came from Rwanda and once the paperwork make it made it to Rwanda, the process was pretty quick.
arrived in US on Oct 10, got married on Nov 5, filed paperwork for AOS, travel and work permit in Dec. Received work approval in February, did biometrics in April, had aos interview in May, received green card in early June. Never received travel permit, but niw we don’t need it.
what is sad, my mother-in-law in Rwanda applied for tourist visa and was rejected immediatly(no discussion or questions).
overall the process was long and the information was very tedious- but certainly worth the effort.
good luck
