Equivalent Of ORDER BY [field] IN (…) In SQL Server

Hi,
I have small question regarding ORDER BY clause.
 
I wanted some value of the fields should come first before other values….Something like:
 
+----------+----------------------------------------+
| code
     | name
                                   |
+----------+----------------------------------------+
| UK
       | United Kingdom
                         |
| US
       | United States
                          |
| AF
       | Afghanistan
                            |
| AL
       | Albania
                        
       |
| DZ
       | Algeria
                                |
| AS
       | American Samoa
                         |
 
I want to display country UK and US code first and then rest of the countries using SQL statement. I know in MySQL, I can use ORDER BY code IN (...)

 

--SQL

SELECT * FROM countries ORDER by code IN ('UK', 'US') desc
 
But not sure how can I do same thing in SQL Server. Is there any equivalent of ORDER BY [field] IN (…) clause in SQL Server???
Though I can create a new field something like sequence and use it to display these countries but I can not do that…
Please advice.
 
Thanks,
