Some recommend uploading new I864 if anything has changed or if its more than a year old. Definitely take recent payslips with you, the 2022 tax transcripts as you will interview after April 18 If you can also upload these to CEAC do so.
If you have lived in the country, where the PC is from, for more than 6 months since the issue of the PC, then you need to get a new one. If its from a country where you havent lived since you got it then you do not need another one
