HELP! i have a visa question for Aruba!?

Hi, I'm a Philippines citizen who is currently in the US and processing my green card/permanent residency. My husband and I are planning to take a trip to Aruba, next month June. I learned from this website a href="http://arubacarnival.com/travel/toaruba/index.html#WHERE_AND_HOW_TO_APPLY_FOR_A_VISA" rel="nofollow"http://arubacarnival.com/travel/toaruba/…/a that being a philippines pport holder, I belong to the List B category (the category that needs a visa to go to Aruba) but the exemption to the rule is if i have a greencard and a pport that I'm not going to need a visa, however, I'm still processing my greencard since I just got to the US 3 months ago. I do have doents that prove I have a pending petition for a green card and my US visa is valid for 2 years so I can leave and re-enter the US without problems. Has anyone here who has been under the same predicament and what did you do? And any advice would be appreciated.. thanks!
