US Immigration from Yemen

How long does the transfer take to be completed and how long will take for interview??

we filled petition at Guangzhou office 5 days later we got an email additional processing requirements and interview

we requested delay the interview

has anybody had this issue ???

we filed the petition I-130 at the us Guangzhou office , I was told in 60 days is the whole processing time , when should I expect the Noa1 as they did not provide us it

My Case is a CR1/IR1 and has been completed since January 8th 2019 and I m line for interview almost 6 months and still no interview
