Transact SQL :: Openquery Update With A Parameter?

I need to update an Oracle table from SQL Server. I am trying to use Openquery Update statement. I need to pass a integer as a parameter. I will be updating a date field and a status field.

This is the gist of what I need to do in a stored procedure

DECLARE    @ID1        INT,
        @SQL1        VARCHAR(8000),
        @STATUS     VARCHAR(10),
        @DATE        DATETIME;
SET        @ID1 = 350719;
SET        @STATUS = 'COMPLETED';
SET        @DATE = GETDATE();
SELECT    @ID1;
SELECT  @SQL1 = 'UPDATE OPENQUERY(NGDEV2_LINK2, ''select DM_IMPORT_STATUS, DM_IMPORT_DATE FROM NEXTGEN.PARTY_HISTORY WHERE PARTY_HISTORY_ID =  ' + CAST(@ID1 as nvarchar(30)) + ''')'
SET DM_IMPORT__STATUS = @STATUS, DM_IMPORT_DATE = @DATE;
EXEC (@SQL1);
