You can call the IRS toll-free at 800-829-1040 to check the status of your W-7.
@Panky, @Yesemmu has stated that the ITIN has already been received.
For those who wish to speed up the process of obtaining an ITIN, it is possible to get it done quicker than sending original documents to the IRS. This can be done through an Acceptance Agent - a person who has been designated by the IRS to verify the authenticity of required identification needed to apply. More information can be found on the IRS website, including a list of acceptance agents in your area.
