US student visa processing: Few weeks to months.

The processing time for a US student visa (F-1 visa) can vary. Generally, the process includes the following steps and approximate timelines:

1. SEVIS Fee Payment: Pay the SEVIS fee and receive a receipt (1-3 days).

2. DS-160 Form: Complete and submit the DS-160 form online (1-2 days).

3. Visa Appointment Scheduling: Schedule your visa interview at the US embassy or consulate (wait times can vary from a few days to several weeks, depending on the location and time of year).

4. Visa Interview: Attend the interview and provide all required documentation (the interview itself usually lasts around 15-20 minutes).

5. Visa Processing: After the interview, visa processing typically takes 1-2 weeks, but it can be longer if additional administrative processing is required.

In total, it can take anywhere from a few weeks to a couple of months to complete the entire process. It's advisable to start the process as early as possible to account for any potential delays.
