To retrieve group memberships for a user across different domain, you'll have to connect to domain's Active Directory separately, and then query for the user's group memberships in that domain.

# Prompt for credentials
$credential = Get-Credential

# UserID to search for
$userID = 'yourUserID' 

$domain = 'yourdomain.com'

# retrieve group memberships
Write-Host "Checking $domain"
   
# Connect to the domain's AD
$domainContext = New-PSDrive -Name AD_$domain -PSProvider ActiveDirectory -Root "" -Scope Global -Server $domain -Credential $credential
        
# Check user's group membership in the domain
$user = Get-ADUser -Identity $userID -Properties MemberOf -Server $domain -Credential $credential

$groups = ($user.MemberOf | ForEach-Object { (Get-ADGroup -Identity $_ -Server $domain).Name }) -join ', '

Write-Host "User $userID is a member of the following groups in $domain: $groups"
