if you are coming to qatar on a tourist or business visit visa, you do not need to have your TOR & diploma authenticated (for travel purpose documentation) unless you are planning to join a company which needs authenticated docs.

i would recommend you have your docs authenticated and bring it to doha just in case when you apply for a job here and it is required.

usually the business visit visa is preferred by sponsoring companies when they require your immediate deployment as this is very fast to process (1-day) but usually valid only for 14-days so once you arrive here in a business visit visa, the sponsor will have your visa extended for 3-months.

for the tourist visa, i think the validity is 6-months but the processing would be little bit longer (1-2 weeks?).
