No, for them to be included as dependents on your return, as xmasbaby0 mentioned they must have either an SSN or an ITIN.
To apply for an ITIN, complete IRS Form W-7, IRS Application for Individual Taxpayer Identification Number, with the application you will have to submit identifying documents for each applicant. You can mail the W-7 and documentation to the address in the Form W-7 Instructions.
