What to expect at port of entry in this case

[Krish735]

I have applied for B1 US visa but got the stamping for B1/B2. I have stated my intended date and time of travel as Sep 1st and 2 weeks in DS-160 and told the same during my visa interview when asked about it. Can I visit US in Dec and just for tourism purpose. Will it be a problem at port of entry?
Do the immigration officers have access to what I have filled in DS-160 or said in the interview?

No Issues..

No issues, if you travel bit late... Upon Visa grant you need to enter US within 3 months I believe.. Not sure about latest rule..

Thanks for the response SUDHAN but one doesn't have to travel within 3 months after issuance of visa. You can travel anytime before the visa expires. My concern is more about the purpose of the visit. If it will be a problem at the port of entry in the below mentioned case or not.
