Hi Jems, it depends on where you filed your application. If your application was filed with USCIS, you can check the status of your petition/immigration request by visiting USCIS Case Status Online (I am not able to post the link here in the answer, but feel free to Google that phrase and input in your USCIS receipt number into the system for an update).

Alternatively, if you have applied for a visa (either nonimmigrant or immigrant) from a consulate abroad, you will want to look for the Consular Electronic Application Centers "Visa Status Check" and enter in your DS-160 case number (for a nonimmigrant visa) or your NVC Case Number (for an immigrant visa).

Just check your visa status online through the official USCIS website or contact the embassy handling your application.
