Exact year of immigration in ATUS/CPS

In the ATUS and CPS, the year of immigration variable (yrimmig) is coded into categories, but I want the exact year of immigration. Since the text of the question is “When did this person come to the United States to stay?”, is it possible to access the exact year given in the original answer instead of these categories? Do I have to go through the BLS? Is it restricted access?

Although the survey question seems to ask for the exact year, the CPS actually provides response categories for respondents. To see this, you can look up the variable PRINUSYR in CPS monthly record layout file. So, I’m afraid the exact year of entry is not available. I’m sorry for the inconvenience.
