Question--I received my non-immigrant B visa (I have worked in Thailand for 5 years but had to cancel my visa due to being abroad during my renewal time).

I did not expect to get my visa so quickly and would now like to move my flight up a week (3rd of April). My ticket is flexible. Will this be a problem at all since I mentioned my initial flight (10th of April) for my visa application? My visa does not mention anything about my flight date and was granted on March 14th.

Thanks so much.
