Below are the current processing time estimates from the USCIS Service Center in California as of February 28, 2010:

The following are processing time estimates for the USCIS Vermont Service Center as of February 28, 2010:

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.

Visa Processing Times By Visa Category

The category of visa can have a crucial bearing upon how long it will take to process the visa application. This would seem to be due to the fact that more people tend to apply for certain visa categories, while others are requested less often.

A case in point, far more Immigrant visa applications are submitted than K-3 visa applications. This may be due to the fact that the immigrant visas confer a Green Card or because a K-3 visa application  requires a second petition. Some visa categories may take longer to process because there is heightened scrutiny of the visa application during its adjudication.

This author believes that Immigrant visas, also known as CR-1 or IR-1 visas, which confer permanent residence are scrutinized more carefully because of the privileges attached to the visa. An IR-1 visa beneficiary enters the USA with unconditional lawful permanent residence, the IR-1 beneficiary may remain in the USA indefinitely, provided he or she does not commit some sort of act that results in deportation.  Compare this scenario with a K-1 visa application where the visa ultimately obtained will only entitle the beneficiary to 90 days in the USA and require a further adjustment of status application and one can begin to understand why the applications for the K-1 visa seem to process faster.

All of the above processing estimates are an accurate, but approximate, depiction of USCIS processing times at the time of this writing. As a practical matter, USCIS seems to take more time for adjudication of some of the categories mentioned above than for others. Further it should be noted that the US Embassy in Thailand and the National Visa Center can add time to these estimates if they are processing large caseloads. For more specific information regarding visa cases filed at a USCIS service center and being processed at the American Embassy in Thailand please contact info@integrity-legal.com.

Expatriates living in Thailand may be able to file a visa petition at the USCIS office in Bangkok. By doing so, the processing time estimates are different in comparison to filing in the USA. Generally, when one petitions for an immigrant visa locally, they can expect to obtain that visa in much less time than those compelled to file in the USA.
