Check if user exists in group - powershell

Question

I cant get this script to give the right output, I want to check if a user (from the Users.csv) exists in a group (there is one group in each domain, this is a multi domain environment).
I think the problem lies in the second foreach.
Right now the output is the right numbers of lines for each domain, but they all say :
aa#aa.aa bb#bb.bb does not exists in the group PSO_StdPasswordPolicyWithNoAccountLockout
Where it should say:
aa#aa.aa does not exists in the group
PSO_StdPasswordPolicyWithNoAccountLockout
bb#bb.bb does not exists in the group
PSO_StdPasswordPolicyWithNoAccountLockout
Users.csv contains EmailAddress, DisplayName, objectGUID
Clear-Host
$user = Import-Csv ".\Users.csv"
$group = "PSO_StdPasswordPolicyWithNoAccountLockout"
$domains = (Get-ADForest).domains
foreach ($domain in $domains) {
Write-Host ="********** - $domain - **********" -ForegroundColor Yellow
$members = Get-ADGroupMember -Identity $group -Server $domain | Select-Object objectGUID
$exportMembers = $members | Export-Csv .\RemoveUsersTemp\$domain.csv -NoTypeInformation
$importFile = ".\RemoveUsersTemp\$domain.csv"
$amembers = import-csv $importFile | Select-Object objectGUID
foreach ($amember in $amembers) {
If ($amembers.objectGUID -contains $user.objectGUID) {
Write-Host $user.EmailAddress"exists in the group $group " -ForegroundColor Green
}
Else {
Write-Host $user.EmailAddress"does not exists in the group $group" -ForegroundColor Red
}
}
}

This is because you use $user in the second loop, but you're not looping $user, so you're referring the whole $user array, which has the content of users.csv.
