Yes, you can apply for the Tanzanian visa online unless you do not fall into the category of those nations who need to apply for their Tanzania visa in advance. However, if you do qualify for applying online, you will be required to fill in the online form, make payment as required and submit the application online. The visa application will be reviewed internally and processed within ten days and you will be notified through your email whether you have been granted or rejected a Tanzania visa. You can also track the status of your application through the online system. Those applying for online visas should apply keeping in mind the processing time it takes for the visa. Citizens of some countries or some individuals may be called for an interview as well at your nearest Tanzanian embassy or a consular office.
