Welcome to Doha, Mr. Sayed.

First I'd like to know if ur visa for tourism, visit, or open?

If you are in a visit, so u have to search for any company or sponsor to have a job and then u will get a work visa.

If u have a tour visa, then its a different matter.

For open visa, I think there is no problem for staying until u get a job.

Anyway, exert ur utmost effort to find a job, any job, then it will be Ok.

I wish I could help u
