It depends on your skills and mother language. There are quite a lot of opportunities out there for freelance translators, writers, copy editors etc. Often, companies need machinery or medicine handbooks translated into various languages, not just English. Most of these jobs are freelance so you can work from home. I don't have any experience with data entry jobs but I presume that it's best to look for those jobs on overseas job sites. You would then have to work on "overseas" time.

Thanks Redaria, I learned some new from your answer.

I heard some "capcha entry" thing...any idea ?

Here are a few legit wok from home sites , gzraj.

Staff.com https://www.staff.com - this site offers FULL TIME/part time jobs to everyone who is interested in having a steady income at home. Simply post your detailed resume with a short intro of yourself and expect for a job interview if you're resume fits to the job position.

Fiverr http://www.fiverr.com - if you have talents/services/skills that are exceptional, you can post them here. Every service/gig starts at $5 but you can always increment them if you are willing to offer more.

Thanks jr20 , I will definitely try them.
