How can I find a native speaker who can speak with me for free in the site?

Of course, you ask nicely. :) You can find people willing to help or do a language exchange here: http://www.italki.com/partners A couple of other options are to fill in your profile a bit more (say whatever you want, but just enough so we can see you're human) ;) and be active on the site: ask/answer questions, join discussions, chat or write/correct notebook entries.

Dalal: My schedule permitting, I can work with you, but not "on this site". If you have or get a Skype account, I can work with you; but I have a heavy case load of students, and you may have to choose a time that is convenient in terms of my schedule.---Warm Regards

You need luck and perseverance.

Hi Dalal, here are the italki English /Arabic speakers. Message some members and I hope that you will have some great language partners soon!

Thank you so much Once I get a skype account I'll contact you Best Regards
