That will depend on the adjudicating officer.
J Charles Ferrari Eng & Nishimura 213.622.2255 The statement above is general in nature and does not constitute legal advice, as not all the facts are known. You should retain an attorney to review all the facts specific to your case in order to receive advise specific to your case. The statement above does not create an attorney/client relationship. Answers on Avvo can only be general ones, as specific answers would require knowledge of all the facts. As such, they may or may not apply to the question.
What you're not asking is whether or not immigration will accuse you of having pre-conceived intent to be a student ... even though you used a tourist visa to enter the US.
Someone probably told you about the 30/60/90 day presumption of having misrepresented intent when entering the US in one visa and then 'quickly' changing to a different visa. Right?
So ... here's the bottom line ... did you misrepresent your intentions when you entered the US? In other words,did you plan to be a student ... even though you entered as a tourist?
If so ... go meet in private with a lawyer ... he/she might be able to help you put a positive 'spin' on this misrepresentation of your true intentions.
