Hi guys, i'm glad i found this website, I've been looking around the internet for a solution to my problem. 
Long story short, i overstayed my chinese visa for a while back, in 2013 i went for a voluntarily exit and after a month long waiting i finally got my exit visa. Which had a note "Requested to leave China in 10 days" , at that time i wasl in love with a chinese lady and she decided to follow me back home. We got married in my home country and then applied for a new chinese visa. Prior to coming home my then GF asked the immigration officials if i could come back and they told her that i could after 3 months.
While applying for the visa in my home country with my wife we stated on the forms that i had a previous overstay and explained in a separate sheet why i overstayed.
We got the visa which was at that time an (L) tourist visa and then came back to china.
While in China i was able to extend it for an extra one month. After that i tried to get the then family reunion resident permit which was available to Foreigners with Chinese Spouses.
It was then the immigration officer in Guangzhou called us for an interview and told us that i will have to return to my home country because i have an overstay record.
Non of the explanations and apologies and my wife's wailing could do anything. All the officers said was that i couldn't return to China unless after 5 years.
Now it's been almost a year and half and my wife have visited me Three times. Upon returning on her last visit that we realized that she's pregnant.
Now my question is, i will like to visit her for a month and then return and probably be there while my child is being born. How are my chances of being given a visitor's visa to visit my wife, in this situation? 
Any help is really appreciated.
Thanks
