I still think localized programming languages are a good first introduction for students with low English proficiency. The less initial barriers there are for the student, the easier it is to gain interest. Moreover, it takes students a while to realize that a programming language is distinct from natural language so they are generally more comfortable "programming in a natural language" they are fluent in. It should be easier to move to a programming language with syntax in English once basic concepts are picked up. I've had good experiences using Chinese Python with students.
