If she doesn't have a good job and travel history getting a US visa as a young woman is very very hard to do. Once she has a US boyfriend it is harder.
Other VISA options might be Canada, Caribbean, Central America and Mexico. She can travel to Cuba but transit visa can be hard to get.
Even the consulates in PH are hard to deal with. We didn't initially immigrate to the US. The Mexican consulate in Makati couldn't figure out how to do her residency visa. We flew to Hong Kong and 3 hours and $36 later Mary had a Permanent Resident Visa for Mexico.
