如果I-130还是pending，可以直接联系USCIS把它转为consular processing，不用I-824

看https://www.uscis.gov/i-130：

”If the Form I-130 is still pending with us and you want to change your selection (to either consular processing abroad or adjust status in the United States), you may contact the USCIS Contact Center and request a change. If you want to change your selection after we have already approved the form, you may need to file Form I-824, Application for Action on an Approved Application or Petition.“
