What do I put for last port of entry and entry date?

[Igor Korabel]

I'm in the US legally as an F1 student, but recently went on a cruise. There were no stamps put in my passport. The passport/documents were only visually checked (no computer present) when I returned from the cruise back to Miami. Do I list that as the last port of entry even though there is probably no record of it? Or should I list the location/date when I initially entered the US?.

Also, on Form I-130 do I list my employement at school here in the US. I can work legally in school as an F1 student.

When is your I-94 says, did you got I-94 while entering US on cruise. (Where did u went on cruise, is it outside the US border or just US island?)
If they didn't give you any stamp or I-94 then you can write your first entry.
You can describe you are working at school. (part time).
