Probably a question to pose to the US State Department. Best of luck, Hunt

These days there are lots of street remodels but still possible to take good photos.. recommended

Googled several sites. No answer to when it ends.

Yes, try parking at one of the hotels and if not there are several parking decks. Also ask the individual who set up your Tour 😊

Contact your Congressman. They will have a person who handles the requests for a tour. You need to do it as soon as you can, 90 days prior to your visit. There are limited spots and they fill up quickly.

I’m sorry that I have no answer. Perhaps your congressman can help since they have access to scheduling White House tours.

In the U.S. you have to submit the request within 90 days or less from the time you plan to visit. I don't know what is is for international visitors. Make sure you accurately provide your name. I was almost denied because my ID only has initials for my first and middle names. You can request which days you would like to visit. Choose several and they will pick which one is available.

Contact your congress person. It may be too late. They usually ask you to request it 3 months in advance, but there could be availability so you should ask anyway.

You have to go through your embassy in Washington DC according to the White House website!

You could leave your bags on the tour bus to the White House if you are taking a private one. Otherwise, I would contact the White House Visitor Center and ask them what you should do. Have a great trip. It is a special house.
