Help with script for "Import AD users from CSV with checks first"

Question

Hi everyone.
Can anyone tell me if i am on the right track here?
I want to be able to provide a CSV with users and import into a new AD domain/forest. But i know there already are some AD accounts so i need to run some checks. For now i am checking only on Name and Email.
The issue i have is is with "write-host "$UserFullName was not found. Creating user.". It outputs this 19 times which is the same amount of times as there are users in AD in this OU.
Not sure if my method is right. 
$allImportedUsers=@()
$allUsersArray=@()
$searchbase="OU=PL,DC=EUECS,DC=CORP,DC=ARROW,DC=COM"
$path = "OU=Users,OU=PL,DC=EUECS,DC=CORP,DC=ARROW,DC=COM"
$allImportedUsers = Import-CSV polandusers_edited.csv
$allUsersArray = Get-ADObject -LDAPFilter "objectClass=User" -SearchBase $searchbase -Properties * | select *
$allImportedUsers | ForEach-Object {
$Firstname = $_.givenname
$Lastname = $_.surname
$UserMail = $_.EmailAddress
$UserFullName = $Firstname+" "+$Lastname
$importUserSAM = $_.Samaccountname
$allUsersArray | ForEach-Object {
$currUserFirstname = $_.givenName
$currUserLastname = $_.sn
$currUserMail = $_.mail
$currUserFullName = $_.name
$currUserSAM = $_.samaccountname
$currUserDN = $_.DistinguishedName
if($currUserFullName -eq $UserFullName) {
write-host "CSV $UserFullName matched on name"
$userMatched=1
if($currUserMail -eq $UserMail -AND $userMatched -ne 1) {
write-host "CSV $UserFullName matched on email"
$userMatched=1
if($userMatched -ne 1) {
write-host "$UserFullName was not found. Creating user."
$userMatched=0
If only i had a cool signature!! ;)

Move below to outside the inner for-each loop:
if($userMatched -ne 1) {
write-host "$UserFullName was not found. Creating user."
$userMatched=0
so the bottom should look like
}if($userMatched -ne 1) {
write-host "$UserFullName was not found. Creating user."
$userMatched=0
