I want to know the names of banks that accept other banks' credit card statements for limit enhancement. So please name the banks if someone tried LIMIT ENHANCEMENT with another bank's statement.
Usually no bank actually accepts it unless it's an exception or as secondary supporting documents. Limit enhancement can be requested Primarily through Income Documents and secondarily through the Banking Relationship. If you're an HNI, bank may consider even auto LE faster and on exception basis.
But after submitting income documents you may ask the bank to match or give the same limit of existing card. But in very rare condition they may accept it. The chance is too thin to consider
