How do I get my wife and daughter to the U.S. for just 3 years?

You can sponsor them for green card.

It takes about a year to bring them here. And the green card is the best option.

Your best option would be a green card, despite the plans for relatively short term time in the US.

If you are a US citizen, you can only really apply for their permanent resident status (green card) for them to be able to live in the US on a permanent basis for 3 years or longer, as the case may be. Additionally, if you plan to then go back to the Philippines for good, in order for them to be able to do that and not lose their US status, they would need to get US citizenship after being permanent residents for a sufficient period of time. In order to petition for them, you have to start the process of filing the petition on their behalf with USCIS. Once that is adjudicated and approved, it will be forwarded to the US Consulate in Manila for an interview. Once they pass the interview, they will be issued immigrant visas to enter the US. Please let me know if you have any additional questions or how I can be of further assistance to you in this matter. Thank you,

The only way I see to bring your family to the United States is by filing a family-based visa petition for your wife and daughter. They will come to reside legally in the United States once the visa is approved. If after some time you all decide to move to another country, the US will not stop you or your family from doing so. However, if a resident moves out of the US with the intention of staying abroad, that resident loses his/her residence.
