My lady whom I've known for 3 years is a resident of and lives in the Philippines and wants to visit the US. I'd like to get her some assistance.

She can apply for a visitor visa, but if her intent is to marry you then it would be advisable to petition her for a fiancé visa. If she enters the country and later gets married to you then the immigration officer may ask some tough questions about her preconceived intent. It’s best to let an immigration lawyer assist you both in this process.
