These estimates should not be viewed as accurate for each individual case as each case is unique and some cases take more time to process through the United States Citizenship and Immigration Service (USCIS) and others may take considerably little time to process through the Service Center. In any case, the assistance of a US Visa Lawyer can be helpful to clients as an authorized representative is entitled to correspond with USCIS on behalf of clients and can thereby streamline the overall visa process.

It should be noted that these estimates do not include the time that it takes to get the case processed through a US Embassy or US Consulate overseas. For those processing a Thai case, it usually takes about 6-8 weeks to process through the US Embassy Thailand.
