Chances to have US Visa

[Rose2014]

Hi,

I am currently in Canada with Permanent Resident status and would like to obtain a US Tourist Visa but I have some concerns whether my chances of approval is low because of my previous I-539 has been denied before during my stay in USA.

Here is my visa history:

J1 Visa holder from 05/08/2002-11/08/2003 (USA)

My two-year home residency requirement has been approved March 23, 2003 (USA)

My I-539 application has been denied 04/12/2004 (USA)

My application for Alien Employment Certification has been received by the Employment Development Department has been received 06/14/2004 (USA)

My Immigrant Petition for Alien Worker has been approved July 27, 2007 (USA)

Please advise.

Thank you
