[Tex/LaTex] Adding notation directly under $\arg \min$

math-operators

How do I add the $\theta_t \in \Theta$ in $$\theta_t^* = {\arg \min}_{\theta_t \in \Theta} \mathbb{E}$$ so that it goes directly underneath the $\arg \min$?

EDIT: I should have specified this earlier, but I'm primarily interested in something that would work on stackexchange sites, such as math.stackexchange.

\limits can be applied to a math operator, to indicate that sub/super-scripts should go below/above the operator.

\documentclass{article}
\usepackage{amsmath,amssymb}
\begin{document}
\[
\theta_t^* = \mathop{\arg \min}\limits_{\theta_t \in \Theta} \mathbb{E}
\]
\end{document}
