No, you are not eligible for the Child Tax Credit if you only have an Individual Taxpayer Identification Number (ITIN). To claim the Child Tax Credit, the qualifying child must have a Social Security Number (SSN) that is valid for employment in the United States. This requirement is specified in the Internal Revenue Code and IRS guidelines.
