Sending the stored procedure output as comma-separated rather than multiple rows

I have a stored procedure that returns multiple rows with 5 columns:

SELECT Travel, ID, Dept, Role, Country 
FROM TravelManager

For example, I get:

DName   ID   Dept  Role   Country
----------------------------------
Travel  23   HR    H      USA
Travel  29   MR    M      AUS
Travel  32   FI    M      UK

Is there any way for me to send this as comma-separated values as first column is same, I want to send only one row without duplicating names in multiple rows and also send other columns as one row only as coma separated values.

Any thoughts and better way to do this? Also how would I modify my select query?

My first column is stored procedure input, so returning that as well :)

I was thinking of temp table or table variable but how to do if so? Please help

It can be done by using a cursor

declare @Travel nvarchar(max)
declare @ID int
declare @Country nvarchar(max)
declare @Dept nvarchar(max)
declare @Role nvarchar(max)

declare @string nvarchar(max)

declare cursor1 cursor for
     SELECT  ID, Dept, Role, Country 
     FROM TravelManager

set @string = '';

open cursor1

fetch next from cursor1 into  @ID, @Dept, @Role, @Country

while (@@Fetch_Status <> -1)    
begin
    set @string += convert(varchar(10), @ID) + ',' +
                   @Dept + ',' + @Role + ',' + @Country + char(13) // char(13) for new line
    fetch next from cursor1 into  @ID, @Dept, @Role, @Country
end

close cursor1
deallocate cursor1


select  @string as ReturnValue

char(13) adds the carriage return else you can add \n I guess

Edit: removed selecting Travel
