HI, If I am moving form India to USA. can I use the same adsense. what is the process to update my payment details.
Although you can do that, the 'Country' fields cannot be changed. https://www.google.com/adsense/support/bin/answer.py?answer=32841&topic=8431
Country field can't be changed.. however, the following tips will help you with the account 1)You can email them and explain your case. Maybe show them the proof of moving. 2) You can ask them to close down the current account and open a new account with US address. They will transfer the money from old to the new one. Hope thats helps. Reps appreciated.
An easy option would be to get a new publisher id. If for some reason you do not want to do that, you can actually change all details and as others suggested email them and get your info updated.
Instead of opening a new ID, I would advice you to change the address by contacting the Google Adsense team.
creating new account is not option try to contact adsense team, tell them about your situation and show your proof of moving from one country to other They have some resolution regards these.
The original question was asked in 2007. I am sure the OP is now in USA and done what he/she wanted to do. By the way, now Google has stopped check payment in countries with EFT option. So if someone moves to US, they would have to quickly open a bank account in a US bank in order to enable EFT.
