Current status data occur in contexts including demographic studies and tumorigenicity experiments. In this case, each subject is observed only once and the failure time of interest is either left- or right-censored. Many methods have been developed for the analysis of such data , most of which assume that the failure time and the observation time are independent completely or given covariates, which may not hold in many situations. In this paper, we present a sieve maximum likelihood approach for current status data when independence does not hold. A copula model and monotone I-splines are used and the asymptotic properties of the resulting estimators are established. In particular, the estimated regression parameters are shown to be semiparametrically efficient. An illustrative example is provided
