We sent off the I-130 on May 9th and it was recieved May 11th but we still have had nothing in the mail from them. It seems everyone else gets a reciept from them within a week and now its been over 2.
Should we call, you think there is a problem?

no i would chil for another week.

My dates are same as yours. Recently i saw someone from may 5th receive a recipt notice. Yours and mins should be in next 10 days I guess. Did your check clear ? I call INS everyday to ask and last friday when I called them they did not mention mechanical failure so i think it is up now.
