Preventing "Muslim immigration to USA" comes hand-in-hand with Muslims withdrawing their money from US-economy, financial-actors from Muslim countries dumping their investments into US government (bonds).
USA could freeze bank-accounts and prevent money from leaving USA, but it would send the wrong message to China, which is biggest lender to US government.
The reason the USA is competitive is its ability to attract all the foreigners to its University system. All these Muslims would study elsewhere, and after study there's always a 50/50 chance integrating into economy.

It would be great for the other countries competing with the USA for that money and talent, if the USA withdraws from that competition all by itself.
