If I want to use a 2-stage opamp for the current to voltage converter application, How should I check for the stability of the circuit? Will it need any kind of stability correction? An uncompensated 2- stage opamp is unstable as voltage amplifier with feedback.

If, as you said, an uncompensated 2-stage amplifier is unstable then you have answered your own about whether or not you need compensation.
To check for stability, I would create a circuit simulation at the transistor level that includes all relevant parasitic capacitances and resistances. Then perform an ac simulation out to a few megahertz, looking for changes in gain. You might also want to run transient simulations while slowly sweeping the frequency. Be sure to do this for a range of dc bias conditions.
