Approx. what percentage of conditional removal green card petitions are scheduled for an interview by USCIS?
Exact statistics are not available. Generally, after receiving the joint petition, the USCIS service center reviews the filing to determine whether to waive the interview - if the USCIS is satisfied that the marriage was not for the purpose of evading the immigration laws, the interview will be waived and the petition approved, otherwise, interview is scheduled. To answer your question, 100% in cases where there is a doubt about the marriage. In other cases, no one knows.
It depends on what you mean by "conditional green card petitions." If you mean the adjustment of status, the answer is 100%. If you mean removal of the conditions on the card, the answer is less than 100%.
