visitor visa Port of Entry

[appuk]

Hi u there
My parents recently got their visitors visa and iam the sponsor for them i stay in sanfrancisco and my question is do they need to enter here only in sanfrancisco or their port of entry can be some other place.
like we want them to come to newyork first ,visit some relatives there see niagara , east side first and then come to west.
is it ok or the immigration officials will object as sponsorer in in california.

please can some body reply to us fast as we r waiting for booking the ticket and want to clear this doubt.

thanks

They can enter from anywhere they like. Just be ready to answer what is going on.
