This depends on which border, what your nationality is, and whether you have any goods that require paying customs on.
In the simplest case, you just walk, drive, catch a bus or catch a train across without even slowing down.
This is the situation in the "Schengen" countries of the European Union where all border controls have been abolished. Here there is only a sign beside the road.
In more typical case you would have to show your passport. This could take anything from a few seconds to hours. They may:
- Just look at your passport and wave you on.
- Stamp your passport and wave you on.
- You may need a visa (permission to enter the country obtained in advance). This is either a stamp or a separate document. If you need this they may check it.
- The customs may want to check through your luggage. In which case you may be asked to go to a customs building with your luggage.
- The customs will ask "have you anything to declare".
If you are driving a goods vehicle with commercial goods (imports and exports), the customs will want to check your paperwork, possibly inspect the load, and possibly they will charge you customs duty. This could take hours.
Finally, there are some borders which are "closed". You are not allowed to cross them.
The conclusion is, it depends on the border.
If you are a US citizen and have the identification for it then Yes you can if you are to travel by land and sea. If by air, you need your passport.
No.
you need a tourist visa, because you are still a citizen of India and not canada.
If you are a US citizen you will never be denied the enter to your country. However, you will need to show a valid passport in order to cross immediately If you don't possess a valid passport, you will be asked to step aside to prove your citizenship, which is a process that might take 10 mins or 2 hours depending on the situation. If you are crossing the border recurrently without a passport you might be subject to fines.
Not yet. But things will change in the spring of 2009.
A passport is needed to cross any international border.
A passport of some kind is needed to travel into the United States if not a citizen.

Yes, if you have a US ID and cross the border by car or foot, you will be OK.

You do not have to have a driver's license in order to enter the US, you just need a passport. Of course, if you plan to cross the border by driving a car, then you do need a valid license, but you legally need a license to drive any time you are driving a car, whether it involves crossing a border or not. If you are arriving in the US by plane (or by any other mode of transportation) no license is required.
