hello. i would like to ask if there are any restrictions with regards to how frequently a person can use his/her multiple entry tourist visa within a year.. lets say.. these are the travel dates.. first visit: august 2007-december 2007 2nd visit: august 2008-january 2009 im planning to go back to the US by 1st week of may 2009, for tourism/shopping and to visit friends/relatives will there be a problem knowing i spent 4 months in my home country? will i be questioned by an officer at the poe? what are the chances of me being denied an admission? your opinions would gladly be appreciated. thank you very much and godbless.
