Yes, ezW2 can generate EFW-2 file for Guam. But ezW2 cannot support GUAM W2 W3 white paper printing. Below is our suggestion.

1. Download ezW2 software free demo version. No obligation. No credit card required.

2. ezW2 can fill in data only on pre-printed form.

You can download Guam form and test this feature.
