How much time does one have to prepare an RFE response?

[f74]

For instance, I might be interested in delaying my response for RFE. What is considered to be an acceptable delay and wouldn\'t cause some additional questions from INS?

you get 90 days to reply to an RFE.....

better not delay after that period - unless justifiable - good luck
