Yes, you need it. You cannot get it at the border. You can apply for a tourist L type in Doha. You need to provide your passport and its copy, the application form with a passport-style photo attached, round trip air tickets, and hotel reservation, as well as residence permit in Qatar. After you submit the application, 4 working days will be needed for the process.
