Travel to Puerto Rico w/ H1B visa w/o the stamp?? Help!

[lovesummer]

Hey guys,
I have some questions about traveling to Puerto Rico. I'm a Chinese citizen
with a Chinese passport. I'm current on H1B visa. However, since I haven't
gone back to China since 2006, my I-94 still has the student visa, without
the H1B visa stamp. Can I still travel to Puerto Rico without any hassle?
What traveling documents do I need? If you have experience in traveling to
Puerto Rico and have suggestions, please kindly let me know. Thanks a bunch!
