We study the interplay of spin-orbit coupling (SOC) and strong p-wave interactions to the scattering property of spin-(1)/(2) ultracold Fermi gases. Based on a two-channel square-well potential generating p-wave resonance, we show that the presence of an isotropic SOC, even for its length being much longer than the potential range, can greatly modify the p-wave short-range boundary condition (BC). As a result, the conventional p-wave BC cannot predict the induced molecules near p-wave resonances, which can be fully destroyed due to strong interference between the s- and p-wave channels. By analyzing the intrinsic reasons for the breakdown of the conventional BC, we propose a p-wave BC that can excellently reproduce the exact molecule solutions and also equally apply for a wide class of single-particle potentials besides SOC. This work reveals the significant effect of SOC on both the short- and long-range properties of fermions near p-wave resonances, paving the way for future explorations of interesting few- and many-body physics in such systems.
