I cannot use iPhoto now there is Photo on my mac. How can I continue to use iPhoto

You can, why do you think it's not possible? Does need updating?

Go to the App Store and check out the Purchases List. If iPhoto is there then it will be v9.6.1

If it is there, then drag your existing iPhoto app (not the library, just the app) to the trash

Install the App from the App Store.

Sometimes iPhoto is not visible on the Purchases List. it may be hidden. See this article for details on how to unhide it.

One question often asked: Will I lose my Photos if I reinstall?

iPhoto the application and the iPhoto Library are two different parts of the iPhoto programme. So, reinstalling the app should not affect the Library. BUT you should always have a back up before doing this kind of work. Always.

I TRIED TO UPDATE IPHOTO APP BUT APP STORE SAYS IT IS NO AVAILABLE IN THE U.S. SO NOW WHAT?

Did you try the method outlined in TD's post. If you did try gain but first move the current iPhoto application to the Trash bin in the dock before going to the App Store.

1 - fix your Cap Lock key - All Caps is rude and is hard to read

2 - ThreadJacking is also Rude and confuses you and the OP since no one knows which answer pertains to which question - start a new thread with a new problem

3 - TD gave very specific instructions which apparently you choose not to bother with - follow them and you will be fine - if you have a problem then you need to start a new thread and give specific details
