Fix your constructor as GrandFather indicated, and your code 'works'. You probably did not intend to output a reference to a filehandle. I have made your test case the default input, and added one line to print $row.
BEGIN{
$ARGV[0] //= \qq(Importance,Company,Department,"Job Title"\n);
}
use v5.10 ;
use strict;
use warnings ;
use Text::CSV ;
use FileHandle ;
my $csv = Text::CSV->new({binary => 1}) ;
my $fh = new FileHandle ;
open( $fh, "<", $ARGV[0])
or die "Can't open $ARGV[0]: $!\n" ;
say $fh ;
my $row = $csv->getline($fh) ;
say do{ local $" = "\n"; "@$row" };
exit
OUTPUT
FileHandle=GLOB(0x8bba28)
Importance
Company
Department
Job Title
You do not need both FileHandle and open. Either one will do the job.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
