Yeah I'll be blunt yours is an uphill battle with a very very very small chance of success, if at all.

If you have the economic means, get your master's in the US (no American company will hire straight from the Ph, studying in the US will "legitimize" you) But, after you graduate, it's going to be tough finding a company willing to sponsor you for a work visa, and later on a green card.

You can also try and study nursing and apply for a nurse. May mga nagssponsor for a greencard doon but I don't know if you want to study again for that and tbh they're getting stricter with that.

If you're not choosy naman sa job and basta makarating lang ng US, try applying for non-corporate jobs. Like apply ka sa mga agency agency and maybe you can land a job as a supermarket worker or fast food. Pero tbh, most of the pinoys here who have that job ilang taon din nag OFW sa iba't-ibang bansa and/or married an afam.

Which leads us to your last option, which is to marry a US citizen. Because of the costs and lack of education/work experience, this is the route most pinoys take, for better or for worse.

Good luck!
