Owning a property in the U.S. does not automatically grant you residency. Instead, the amount of time you can remain in the country will depend entirely on the type of visa you hold. For example, a B1 (business visa) or B2 (visitor visa) is typically valid for six months and can sometimes be extended. Other types of visas, such as the H1-B, grant foreign nationals permission to work and reside in the U.S. for a few to several years. It is best to consult the U.S. Department of State website on any matters regarding U.S. visas and residency requirements.
