I am the joint sponsor for the visa petition for a nine year old child of a Lawful Permanent Resident (LPR), the I-130 for this child was approved in February, 2016 however the petitioner chose (for various reasons) to delay moving forward with the visa process at that time, in late 2018 the mother (petitioner) received her Permanent Lawful Resident / green card status. This year the petitioner has decided it is important for her daughter to be with her in the US and has determined to proceed with the final steps in the visa process. The Petitioner is an unmarried LPR. I have paid the two required fees (Immigrant and AOS) and have received a receipt. The petitioner and I have recently submitted the AOS forms I-864.
I am confused as to whether the June 22 Proclamation of Trump "suspends the immigration" of the beneficiary in this case or if there is an exemption for minor unmarried children of LPR's. Also, it may not be relevant however the beneficiary is a citizen of Nicaragua. Also, I am confident that the petitioner has not received any "public charge" benefits which might affect the visa petition.
So, my question is whether this child beneficiary of this visa process as outlined above is not eligible for immigration at the present time (currently through the proclamation time of December, 2020 which can be extended) or is exempt from that proclamation. I apologize in advance if this question has already been asked and addressed on this forum.
