Could this be a problem in getting visa?

[zion]

I've got an Assistantship offer, but there's a minor mistake in address ( Zip code wrong). Now, I've to attach this letter for getting I 20 form. My prof is out of station and will return by 14th. Should I go ahead with the old offer letter or should I get new offer letter signed by the prof?

Hi Zion,

I hope this response would be in time for you, judging that you posted that question in June. Here's my two cents worth...

It's highly unlikely that you would be denied a student visa primarily due to a typo ( in your case, wrong zip code). Just ensure that the spelling of your name, and its order are right (first, middle and last name). If you are denied a student visa, it would be advisable to contact the international coordinator or graduate school representative dealing with international students. They are usually the life-savers in such situations.

Hope that helps!
